Windows Server 2025 with Visual Studio 2026: v143 build tool for ARM64 is missing

[maron2000]

Description

I understand the following v143 build tool is added for compatibility, as documented.
Microsoft.VisualStudio.Component.VC.14.44.17.14.x86.x64

MSVC v143 is added for compatibility

While Intel builds are builing fine, v143 build tool for ARM64 is missing, and the current workflow targeting ARM64 is failing due to that.
Current running image used is 20260525.121 (although I see that a new version is getting deployed)

Edit: I was advised to raise an independent issue rather than reporting this to an existing issue (#14017)

Is it regression?

This happened after migrating to Windows2025 VS2026 runner

Expected behavior

Visual Studio build successfuly for ARM 64 platform using build tool v143.

Actual behavior

C:\Program Files\Microsoft Visual Studio\18\Enterprise\MSBuild\Microsoft\VC\v180\Microsoft.CppBuild.targets(473,5): error MSB8020: The build tools for Visual Studio 2022 (Platform Toolset = 'v143') cannot be found. To build using the v143 build tools, please install Visual Studio 2022 build tools. Alternatively, you may upgrade to the current Visual Studio tools by selecting the Project menu or right-click the solution, and then selecting "Retarget solution". [D:\a\dosbox-x\dosbox-x\vs\libpdcurses\libpdcurses.vcxproj]

Repro steps

Run msbuild -m vs/dosbox-x.sln -t:dosbox-x:Rebuild -p:Configuration=Release -p:Platform=ARM64 -p:PostBuildEventUseInBuild=false -p:PlatformToolset=v143

Hi!

We will take a look at it.

[maron2000]

Thanks for looking into this.
I switched to using windows-2022 at the moment.
I can't use windows-latest since it sometimes uses vs2026 and sometimes not, and there are no common build tool between the two to use.

[maron2000]

Yeah, and I rthink that is a stupid idea, since project file sets a particular build tool and we can't assume which one is available.

[maron2000]

Maybe you already know but there is a v143 build tool targeting ARM64 that should be easily added.
Microsoft.VisualStudio.Component.VC.14.44.17.14.ARM64
