The toolset is not detected

[mmatrosov]

I copied files according to instructions, but toolset LLVM-vs2017 did not appear in the list of toolsets. If I set this toolset manually, MSBuild complaints that this toolset is not installed.

Visual Studio Community 2017 15.6.2

Well for me its working fine (and I also using 15.6.2), can you upload a screenshot of the toolset directory?

Here you go:

This is the error I get from MSBuild:

1>C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\VC\VCTargets\Microsoft.Cpp.Redirect.14.props(47,3): error MSB4019: The imported project "C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.cpp.props" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.

And here is content of corresponding directory (I also copied your files there - with no luck):

weird... it looks like the visual studio toolsets installed in a different place... I didn't know it could happen ;(
is your LLVM-vs2014 toolset works? if so, can I see the content of one of the props files of this toolset?

[mmatrosov]

Unfortunately, LLVM-vs2014 fails with the same error :(

[Arik-Playground]

And normal visual studio c++ projects work without any problem?

[mmatrosov]

Exactly. And I can't say my installation is abnormal in any way.

[Arik-Playground]

Can you use procmon to see from where msbuild is getting the correct toolsets when using a normal VS project? you should filter to show access to a path that contains Toolset.props

[mmatrosov]

I've run procmon, recorded all files accessed by devenv.exe, removed everything except those that have .props extension and removed duplicates. Here is what I got:
