I was building c++ projects with visual studio 2017, and some projects in one sulution have been built successfully, but other projects meet the error as follows：
C:\Program Files(x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\VC\VCTargets\Microsoft.Cpp.Platform.targets(67,5): error MSB8020: The build tools for v141 (Platform Toolset = '141) cannot be found.
I checked the v141 has been installed, and as described before, some other projects are success.

2022-07-18T03:25:16.857+00:00 I found v110, v120, v140 in MsBuild folded, but no v141.
Then I found v141 in these folders as follows:
So I think maybe the vs cannot find the v141 in correct directory.

Besides, please check if the VCTargetsPath system variable exists. You can remove it and build your project again. -

2022-07-26T13:54:48.313+00:00 Hello, are all projects in one solution? Does it create a dependency relationship between the projects?
Can you try to create a new solution and add the projects to the new solution? -

2022-08-03T06:33:09.08+00:00 Yes, there are several projects in one solution. And some projects can build with v141 successfully, and some projects build with the error MSB8020:The build tools for v141 (Platform Toolset = '141) cannot be found
