@rem setup-windows.bat - provision a fresh Windows box for native development\r
@rem\r
@rem Runs on x64 and on ARM64 (Windows 11 on Arm). See the ARM64 block below for\r
@rem what changes on Arm silicon.\r
@rem\r
@rem Before it does anything, it shows the plan - every step it and its two\r
@rem halves can take, marked for this machine - and lets you choose. See "The\r
@rem plan" below, or run `setup-windows.bat /?`.\r
@rem ---------------------------------------------------------------------------\r
\r
@rem ---------------------------------------------------------------------------\r
@rem Host architecture\r
@rem\r
@rem The environment variables are not enough, and the failure is silent. A 32-bit\r
@rem cmd.exe under emulation reports x86 and stashes the real one in\r
@rem PROCESSOR_ARCHITEW6432 - that pair is handled below - but an EMULATED x64\r
@rem cmd.exe on an ARM64 box reports AMD64 with PROCESSOR_ARCHITEW6432 unset, and\r
@rem nothing in the environment contradicts it. Launching this script from an x64\r
@rem shell (Git Bash, for one) is enough to hit that, and measured here it gives:\r
@rem     PROCESSOR_ARCHITECTURE                  AMD64\r
@rem     HKLM\...\Session Manager\Environment    ARM64   <- the real one\r
@rem\r
@rem So take the machine-level registry value as the answer and keep the\r
@rem environment pair only as the fallback. The registry key is per-machine and\r
@rem not subject to per-process emulation, and it is not one of the redirected\r
@rem hives. This is load-bearing now: the architecture decides which packages\r
@rem are installed at all, so reading it wrong provisions the wrong machine.\r
@rem\r
@rem The value drives two things below, and nothing else - winget resolves the\r
@rem installer architecture on its own (native first, then whatever the box can\r
@rem emulate), so the ordinary installs need no help:\r
@rem   - the plan: every x64-only step, VirtualBox included, is marked unavailable\r
@rem     on ARM64 and so never selected (see setup-windows-steps.ps1)\r
@rem   - the summary tells you which tools you got as emulated x64\r

@rem are shadowable by anything earlier on the PATH, and a POSIX `find` on the\r

@rem Can this account elevate? Worked out ONCE, here, because it gates two very\r
@rem different things: the elevated half far below, and a handful of the "per-user"\r

@rem\r
@rem   ALREADY - already elevated. IsInRole(Administrator) is false for an admin\r
@rem             running unelevated under UAC, so this means actually elevated,\r
@rem             not merely capable of it.\r
@rem   PROMPT  - not elevated, UAC on, so elevation can be requested.\r
@rem   NOLUA   - UAC is off machine-wide (EnableLUA = 0) AND this is not an\r
@rem             administrator. Elevation is impossible, not merely declined:\r
@rem             Windows has no prompt to offer. Note that with UAC off,\r
@rem             `Start-Process -Verb RunAs` does not fail - it is silently\r

@rem ---------------------------------------------------------------------------\r
@rem ARM64 is a lean build box, x64 is the full workstation\r
@rem\r
@rem The ARM64 machine here is a small VM, and everything it was installing\r
@rem without a native build was going to run under Prism emulation anyway. So the\r
@rem two architectures now provision different things on purpose: x64 keeps the\r
@rem full set, ARM64 installs ONE C/C++ compiler - MSVC from Visual Studio - and\r
@rem nothing that merely duplicates it or that exists only as an x64 binary.\r
@rem Rust does not break that rule: it is a different language, not a second\r
@rem C/C++ compiler, and its native aarch64 MSVC toolchain links through MSVC.\r
@rem\r
@rem Dropped on ARM64, and which script would otherwise take each one:\r
@rem   Brave.Brave                      here      no ARM64 build; Edge is in-box and native\r
@rem   WinMerge.WinMerge                here      ARM64 build is machine-scope only\r
@rem   LLVM.LLVM                        here      second Clang, dropped with VS's clang-cl\r
@rem   NASM.NASM                        here      x86/x64 assembler; ARM64 uses MSVC's armasm64\r
@rem   Google.AndroidGPUInspector       here      x64-only, profiles Android devices\r
@rem   OpenCppCoverage.OpenCppCoverage  here      x86/x64 only; cannot instrument ARM64 binaries\r
@rem   VS Clang/LLVM component          with-uac  see $ClangComponents\r
@rem   Windows Driver Kit               with-uac  see the WDK step\r
@rem   BinSkim                          no-uac    NuGet publishes win-x64 only\r
@rem\r
@rem The decision itself is made in ONE place, setup-windows-steps.ps1, which\r
@rem marks each of these -X64Only with its reason. The plan shows them as [-]\r
@rem with that reason before anything runs, and :want prints it again in the log\r
@rem where the step would have run, so the skip and its reason stay together.\r

@rem The plan: what this run will do, shown BEFORE any of it happens\r
@rem\r
@rem setup-windows-plan.ps1 lists every step this file and its two halves can\r
@rem take - from the catalog in setup-windows-steps.ps1, marked for this host's\r
@rem architecture and elevation - and lets you switch steps off and on. Nothing\r
@rem below runs unless it was on that list and still selected when you pressed\r
@rem Enter; with no console to ask on, it stops unless given -Yes. Arguments to\r
@rem this script go straight to the planner:\r
@rem   setup-windows.bat -WhatIf                 show the plan, do nothing\r
@rem   setup-windows.bat -Skip VirtualBox,Brave  start with those switched off\r
@rem   setup-windows.bat -Only E -Yes            just the elevated half, no questions\r
@rem\r
@rem The choice comes back as a scratch .cmd of `set` lines, called here:\r
@rem   STEP_<Id>, WHY_<Id>, PKG_<Id>     per step this file takes - see :want\r
@rem   UAC_STEPS, USER_STEPS             comma lists passed to the halves as -Only\r
@rem   PLAN_RUN, PLAN_RC                 go on (1), or stop and exit with PLAN_RC\r
@rem No file at all means the planner failed - it exits 0 even on a mistyped\r
@rem parameter - so that stops the run too, before anything has been done.\r

@rem --- Claude Code, from Anthropic's own installer rather than winget ---\r
@rem\r
@rem NOT `winget install Anthropic.ClaudeCode` any more: recent releases are\r
@rem broken through that route. This is the documented native install,\r
@rem `irm https://claude.ai/install.ps1 | iex`. The script downloads the current\r
@rem release's claude.exe, checks it against the SHA-256 in that release's\r
@rem manifest, and runs `claude install`, which puts the launcher in\r
@rem %USERPROFILE%\.local\bin - per-user, no elevation. Re-running it updates to\r
@rem the latest release.\r
@rem\r
@rem Two things are fixed up around it, both about which build it gets:\r
@rem   - It picks win32-arm64 or win32-x64 from $env:PROCESSOR_ARCHITECTURE and\r
@rem     nothing else - the variable the block at the top of this file shows to be\r
@rem     WRONG in an emulated x64 shell on ARM64, where it would hand you the\r
@rem     emulated build. So %HOST_ARCH%, the registry's answer, is written into it\r
@rem     for the installer's process first. That only corrects the value; anything\r
@rem     else in that process that reads it sees the truth too.\r
@rem   - It refuses a 32-bit PowerShell outright ("does not support 32-bit\r
@rem     Windows"), and a bare `powershell` from a 32-bit cmd.exe is exactly that.\r
@rem     %SystemRoot%\Sysnative reaches the 64-bit one from there - it exists only\r
@rem     for 32-bit processes - so it is used when present.\r
@rem\r
@rem A copy left behind by the old winget route is a second claude.exe, reached\r
@rem through WinGet\Links on the user PATH, and it can win over this one. It is\r
@rem reported, not removed: `winget uninstall Anthropic.ClaudeCode` is yours to run.\r
@rem\r
@rem The installer has no "already current" check - it downloads and reinstalls\r
@rem the whole release every time - so setup-windows-current.ps1 asks first: is\r
@rem the native claude.exe already the latest release, and the build for this\r
@rem host? Only a clear yes skips it; a check that cannot decide installs.\r

@rem --- Non-admin (per-user) winget installs ---\r
@rem\r
@rem No --architecture anywhere on purpose. winget already picks the best\r
@rem installer the manifest offers for this machine - arm64, else x64, else x86 -\r
@rem and pinning it would turn "no native build, use the emulated one" into a\r
@rem hard failure.\r
@rem\r
@rem These all publish real ARM64 installers, so on an ARM64 box every one of\r
@rem them lands as a native ARM64 binary with no emulation involved.\r
@rem\r
@rem The Sysinternals packages are a multi-architecture ZIP rather than an\r
@rem installer, so the ARM64 build is IN there but is not the default-named exe:\r
@rem the zip holds procexp.exe (x86), procexp64.exe (x64) and procexp64a.exe\r
@rem (ARM64). On ARM64, run the *64a.exe variants - plain procexp.exe is the x86\r
@rem one and will run emulated.\r
@rem\r
@rem One :winget call per package, each named by its step in the plan, so any of\r
@rem them can be switched off. Brave is x64-only: the emulated x64 browser is the\r
@rem slowest thing on an ARM64 box, and Edge is in-box and native there.\r

@rem WinMerge is the one package here where winget's own preference order picks\r
@rem the WRONG architecture, and it is worth knowing why: upstream publishes the\r
@rem ARM64 build as a MACHINE-scope installer (WinMerge-<ver>-ARM64-Setup.exe) and\r
@rem the x64 build as a PER-USER one (WinMerge-<ver>-x64-PerUser-Setup.exe). Run\r
@rem unelevated, winget's scope preference beats its architecture preference and\r
@rem you silently get the emulated x64 build.\r
@rem\r
@rem That asymmetry is why ARM64 no longer installs it at all: the only build a\r
@rem normal user can install there is the emulated one, and asking for --architecture\r
@rem arm64 just fails unless the run is elevated. VS Code's diff view and\r
@rem `git difftool` cover the same ground natively.\r
call :winget WinMerge WinMerge.WinMerge\r
\r
@rem --- Build drivers, standalone and native ---\r
@rem\r
@rem CMake and Ninja BOTH ship with Visual Studio, so this is not about making\r
@rem them exist - it is about which binary you get and where it is on the PATH:\r
@rem\r
@rem   - VS's cmake.exe is already ARM64, but it only lands on the PATH inside a\r
@rem     Developer Command Prompt. The build line further down assumes a plain\r
@rem     `cmake`, so install the standalone one to make that true in any shell.\r
@rem   - VS's bundled ninja.exe is x64 EVEN ON ARM64 (verified on this box), so it\r
@rem     runs under emulation. Ninja is re-invoked for every edge in the build\r
@rem     graph, which makes it the one tool here where emulation is actually paid\r
@rem     over and over, and ninja-winarm64.zip is a native build. Worth having.\r
@rem\r
@rem Which ninja wins inside a VS Developer Command Prompt: the native one. VS\r
@rem adds its copy from Common7\Tools\vsdevcmd\ext\cmake.bat with\r
@rem     set "PATH=%PATH%;...\CMake\bin;...\CMake\Ninja"\r
@rem which APPENDS, so the VS directories sit at the very end of the composed\r
@rem PATH, behind every machine and user entry. setup-windows-no-uac.ps1 then\r
@rem pins the native ninja's directory to the FRONT of the user PATH so the\r
@rem margin does not depend on two append orders staying as they are.\r
@rem\r
@rem Ninja here, CMake in the machine-wide group below: Ninja is a portable zip\r
@rem winget unpacks into the user profile, CMake is an MSI that installs for the\r
@rem whole machine.\r
call :winget Ninja Ninja-build.Ninja\r
\r
@rem --- Second, independent Clang: compiler diversity, on x64 only ---\r
@rem\r
@rem On x64 the elevated half installs Visual Studio's Clang component (clang-cl).\r
@rem This is a DIFFERENT LLVM: the upstream release, on its own schedule and\r
@rem usually several major versions ahead of the one VS bundles, installed to\r
@rem C:\Program Files\LLVM rather than inside the VS tree. Two Clang majors plus\r
@rem MSVC over the same sources is the point - it is what catches the bugs a\r
@rem single toolchain agrees with itself about.\r
@rem\r
@rem NOT ON ARM64, and not for lack of a native build - the manifest does resolve\r
@rem to LLVM-<ver>-woa64.exe there. It is dropped because the ARM64 box carries\r
@rem MSVC alone: with VS's clang-cl component gone too, a third compiler with\r
@rem nothing to disagree with is just disk. Do the multi-compiler build on the\r
@rem x64 machine, which keeps all three.\r
@rem\r
@rem PATH ORDER MATTERS on x64 if you use it. Should this installer put its bin on\r
@rem the PATH, a bare `clang-cl` resolves to the upstream one while CMake's\r
@rem `-T ClangCL` toolset keeps using the VS copy - so the two can be selected\r
@rem independently, but only if you know which one you are asking for. Prefer\r
@rem -DCMAKE_CXX_COMPILER with a full path when you care.\r
call :winget LLVM LLVM.LLVM\r
\r
@rem --- Rust, via rustup ---\r
@rem\r
@rem Per-user on both architectures: rustup-init keeps rustup and every\r
@rem toolchain it manages under %USERPROFILE%\.cargo and \.rustup, and puts\r
@rem .cargo\bin on the user PATH. The manifest publishes an aarch64 rustup-init,\r
@rem so ARM64 gets a native rustup.\r
@rem\r
@rem winget runs it as `rustup-init -y -q`, which also installs a stable\r
@rem toolchain for whatever host rustup detects. Which toolchain is the DEFAULT -\r
@rem stable MSVC for this host, x86_64 or aarch64 - is then pinned explicitly by\r
@rem the RustToolchain step in setup-windows-no-uac.ps1 rather than left to that\r
@rem detection; see Set-RustDefaultToolchain there for why.\r
@rem\r
@rem The -msvc toolchains link with MSVC's link.exe, so building needs the Visual\r
@rem Studio the elevated half installs. Installing rustup before it is fine:\r
@rem with -y, rustup-init only warns "installing msvc toolchain without its\r
@rem prerequisites" (rustup 1.29.1, src/cli/self_update/windows.rs) - it does not\r
@rem go and install a Visual Studio of its own.\r
@rem\r
@rem Safe to re-run as it stands. rustup registers itself in Add/Remove Programs\r
@rem under the key "Rustup" - the manifest's ProductCode - and rewrites its\r
@rem DisplayVersion when it updates itself, so winget always sees the version\r
@rem that is really there and only runs rustup-init again for a newer one.\r
call :winget Rustup Rustlang.Rustup\r
\r
@rem x64-only manifest: winget falls back to the x64 installer on ARM64 and it runs\r
@rem under Prism emulation. Harmless for what it does here - iperf3 is a network\r
@rem benchmark bounded by the link, not by CPU.\r
call :winget iPerf3 ar51an.iPerf3\r
\r
@rem Android SDK Platform-Tools: adb and fastboot. A portable zip, so per-user:\r
@rem winget unpacks it under %LOCALAPPDATA%\Microsoft\WinGet\Packages and puts\r
@rem that directory on the user PATH, rather than linking the exes one by one,\r
@rem because adb.exe needs AdbWinApi.dll and AdbWinUsbApi.dll beside it.\r
@rem\r
@rem The manifest labels it x64, but every binary in the zip is 32-bit x86\r
@rem (machine type 0x014C, checked on r37.0.1), and there is no ARM64 build. So it\r
@rem runs under WOW64 on x64 and under x86 emulation on ARM64 - which, unlike x64\r
@rem emulation, every Windows on Arm has. Kept on ARM64 anyway, for the iperf3\r
@rem reason: adb is bound by the USB or TCP link to the device, not by the CPU.\r
call :winget PlatformTools Google.PlatformTools\r
\r
@rem NASM assembles x86/x86-64 only - there is no ARM64 target in it and no ARM64\r
@rem build of it. x64 keeps it; ARM64 does not, because an emulated assembler is\r
@rem only worth carrying if you cross-compile x86/x64 here, and that work belongs\r
@rem on the x64 box. The ARM64 assembler is armasm64.exe, which ships with MSVC.\r
@rem\r
@rem Its installer is also one of the two here that fall back to a per-user\r
@rem directory when it cannot write to Program Files - C:\Users\<you>\AppData\\r
@rem Local\bin\NASM, registered nowhere, so `winget uninstall` cannot find it\r
@rem afterwards. Uninstall.exe in that directory is the only way back out.\r
@rem\r
@rem Registered nowhere also means winget cannot see it is installed, so it\r
@rem reruns the installer on every run - measured, with the same 3.02 on both\r
@rem sides. setup-windows-current.ps1 compares that per-user nasm.exe with the\r
@rem version winget offers first, and only a match skips the install. A\r
@rem machine-wide NASM is registered, so it is left to winget as usual.\r

@rem VirtualBox has no ARM64 Windows host build, and the x64 one cannot be made to\r
@rem work by emulation: a hypervisor is kernel-mode, and its x64 driver will not\r
@rem load on an ARM64 kernel. Installing it on ARM64 gets you a broken product and\r
@rem a failed driver install, so the plan marks it x64-only and says so.\r
@rem\r
@rem This is also what makes setup-windows-7-test-env.bat unreachable from an\r
@rem ARM64 host: it prepares a Windows 7 *x86* guest, and neither VirtualBox nor\r
@rem Hyper-V on ARM64 can run one.\r

@rem\r
@rem Grouped and skipped outright where elevation is impossible. Attempting a\r
@rem guaranteed failure four times per run - and paying the download for it -\r
@rem teaches nobody anything, and the four opaque error codes bury the one line\r
@rem that matters. On an account that can elevate they run exactly as before.\r
@rem The four are -Admin in setup-windows-steps.ps1, so on such an account the\r

@rem than a slowdown: it collects coverage by debugging the process under test and\r
@rem stepping x86/x64 instructions, so it can cover x86/x64 binaries but NOT an\r
@rem ARM64 one. That is what puts it in the x64-only set: on ARM64 it could only\r
@rem ever cover the cross-compiled x64 build, which is a job for the x64 box.\r

@rem --- WiX 5.0.2, pinned on purpose ---\r
@rem WiX packages our proprietary software into MSIs, and the version is pinned to keep that\r
@rem free of a fee. 5.0.2 is the last release distributed under the Microsoft Reciprocal\r
@rem License alone. From 6.0 onward the package also carries OSMFEULA.txt, an Open Source\r
@rem Maintenance Fee agreement: a monthly fee owed by anyone who uses the PREBUILT BINARIES\r
@rem as part of revenue-generating activity and has annual gross revenue >= US$10,000.\r
@rem\r
@rem It is a fee for the binaries, not a restriction on what we ship - MS-RL is file-scoped\r
@rem and never reached the MSIs WiX builds, under any version - but 5.0.2 owes nothing.\r
@rem The 6.x/7.x SOURCE is still MS-RL too, so self-compiling is another way out; a pin is\r
@rem the cheaper one. This replaces `winget install WiXToolset.WiXCLI`, which has no version\r
@rem selector and so installs the latest (7.0.0 today, EULA and all).\r
@rem\r
@rem PIN THE MSBUILD SIDE TOO. A .wixproj referencing WixToolset.Sdk without a version\r
@rem resolves to the latest - 7.x, same EULA - and nothing here constrains it. Pin it in the\r
@rem project: <Project Sdk="WixToolset.Sdk/5.0.2">.\r
@rem\r
@rem dotnet.exe is called by full path: winget put the SDK on the machine PATH a few lines\r
@rem ago, but this cmd session inherited its environment before that and cannot see it.\r
@rem install-then-update is for re-runs - install fails once the tool is there, and update\r
@rem then holds it at exactly 5.0.2 - which keeps this script idempotent like the rest.\r
@rem\r
@rem But update reinstalls even when 5.0.2 is already what is there, so first look in the\r
@rem global tool store, which keeps one directory per installed version under\r
@rem %USERPROFILE%\.dotnet\tools\.store\wix. With 5.0.2 there and its shim in place, nothing\r
@rem runs; install-then-update is left for a first install, or for pulling a tool that has\r
@rem drifted to another version back to the pin.\r
@rem\r
@rem %ProgramFiles%\dotnet is the NATIVE SDK's root on every architecture, ARM64\r
@rem included - what winget just installed. An x64 SDK installed alongside it on\r
@rem an ARM64 box goes to %ProgramFiles%\dotnet\x64 instead, so fall back there\r
@rem for a machine that only ever got the x64 one. Prefer the native root: the\r
@rem ARM64 SDK runs the wix tool natively, and building an MSI is not something\r
@rem worth doing through emulation.\r

@rem --- Elevated installs (Visual Studio, WDK, system tools) ---\r

set "UAC_LOG=%~dp0setup-windows-uac.log"\r
\r
@rem %ELEV% was worked out at the top of this script - see the comment there for\r
@rem why `Start-Process -Verb RunAs` cannot be trusted to report this itself.\r
@rem\r
@rem It is handed exactly the elevated steps the plan left selected (-Only, as one\r
@rem comma list, which it splits) and -Yes, since the question was asked before\r
@rem anything ran. With none selected there is nothing to elevate FOR, so no\r
@rem prompt is raised at all.\r
if "%ELEV%"=="NOLUA" goto :elev_impossible\r
if not defined UAC_STEPS goto :elev_not_selected\r
\r
@rem The last run's log goes only now, when a new one is about to replace it: a\r
@rem run that leaves the elevated half out keeps the log of the one that did it.\r
if exist "%UAC_LOG%" del "%UAC_LOG%"\r
if "%ELEV%"=="ALREADY" goto :elev_direct\r
\r
@rem Not elevated, UAC is on: request it. Expect a prompt - a Yes/No for an\r
@rem administrator, and for a standard account one that asks for an\r
@rem administrator's name and password, after which the elevated half runs as\r
@rem THAT account.\r
@rem\r
@rem Process.Start with the runas verb, NOT Start-Process -Verb RunAs, which this\r
@rem line used to be. Two reasons:\r
@rem   - When Start-Process fails - a cancelled prompt, most often - `$p` stays\r
@rem     empty and `exit $p.ExitCode` exited 0: a failed elevation reported as a\r
@rem     successful one.\r
@rem   - It cannot be told apart even when caught. Windows PowerShell's\r
@rem     Start-Process rethrows the failure as a plain InvalidOperationException\r
@rem     and drops the Win32Exception that says why (checked: a missing program\r
@rem     came back as exit 1, not 2). Process.Start keeps it, so the exit code\r
@rem     here is the real Windows error - 1223, ERROR_CANCELLED, for a declined\r
@rem     prompt - and the message is printed where it happens.\r
@rem If the elevated process does start, its own exit code comes back as before.\r
@rem Arguments is one string, passed through verbatim - the same hand-built form\r
@rem Invoke-VsModify uses in the elevated half.\r
@rem\r
@rem NO QUOTE CHARACTERS INSIDE THE -Command STRING. This line used to wrap the\r
@rem script path in "" pairs, and powershell.exe's command-line parser does not\r
@rem read those the way they look: the first "" yields a quote but leaves the\r
@rem quoted region, and the second - now outside it - yields nothing at all. The\r
@rem path's CLOSING quote vanished. That went unnoticed while the path was the\r
@rem last argument, because an unclosed quote simply runs to the end of the line.\r
@rem Once -Only and -Yes followed it, they were swallowed into the -File path,\r
@rem and the elevated PowerShell refused a script that did not exist (exit\r
@rem -196608) before running a single line: no transcript, and a window that\r
@rem closed at once. Measured with a stand-in that records its own command line:\r
@rem     -File "C:\...\setup-windows-with-uac.ps1 -Only OpenSshClient,... -Yes\r
@rem So the path and the step list travel as environment variables, and the one\r
@rem quote the child needs is [char]34, made inside PowerShell where no parser in\r
@rem between can eat it.\r

@rem      is visible here. Same problem the DOTNET_EXE lookup solves above, and it\r
@rem      would bite even where the launcher IS installed.\r
@rem\r
@rem   2. The launcher may simply not be there. Measured on the ARM64 box: every\r
@rem      other Python component registered - Core Interpreter, Executables,\r
@rem      Standard Library, pip Bootstrap, Tcl/Tk, Add to Path - and there is no\r
