问题
I have upgraded a solution from VS2010 to VS2012. I did that with other solutions, and it worked fine.
But now when I tried to build the updated solution, the compiler tells me:
Error 1596 error MSB8020: The builds tools for Visual Studio 2010 (Platform Toolset = 'v100') cannot be found. To build using the v100 build tools, either click the Project menu or right-click the solution, and then select "Update VC++ Projects...". Install Visual Studio 2010 to build using the Visual Studio 2010 build tools. C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V110\Microsoft.Cpp.Platform.targets 42 5 praat3
I don't know why the compiler tries to use VS2010.
In the project property pages, I see under "Debug source files" the following entries:
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\crt\src\
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\atlmfc\src\mfc\
etc.
Also, if I set the "Platformtoolset" to "Inherit from project above or project standard", it defaults to "v100". I think this is the best hint about what goes wrong here.
By accident I managed to open up the Microsoft.Cpp.Platform.targets file, and I see that v90 and v100 are listed there, but not v110.
Could somebody who uses only VS2012 perhaps have a look at that file?
This is what it looks like for me:

Thank you for the help.
回答1:
The project is set to build with VS2010 compilers (platform toolset). You might have uninstalled VS2010 and got this error.
You can change the platform toolset in project properties->General->Platform Toolset. Change it Visual Studio 2012.
回答2:
Same error for me recently with VS2017.
Turned out the solution was merely missing a dependent project.
If this is the cause, you should see something like:
Done building project "someproject.vcxproj" -- FAILED.
on the next line after the error message:
error MSB8020: The build tools for Visual Studio 2010 (Platform Toolset = 'v100') cannot be found.
This error can be confusing since your projects may have already been retargeted.
回答3:
Under "C/C++", there was a lib in "Additional include directories". I did not use this lib, but it was referenced. I removed this lib.
I also deleted all "studio 2010" entries in the registry.
回答4:
I know this is an old thread, but perhaps this might help somebody else who comes here because of similar issues.
I had a similar problem. VS 2015 Community (MSBuild 14) building a c++ app, wanted to use VS 2010 (v100) tools. It all came down giving msbuild an invalid configuration option. Strange.
So, recheck all those options and parameters.
