Mistake. This version of Visual Studio cannot open the following projects.

Question

I installed the Python package for VS.NET 2013 from VS itself. After that, I could not open any project in C ++. I got this error message:

Full text:

Unsupported

This version of Visual Studio cannot open the following projects. vcxproj Project types may not be installed or this version of Visual Studio may not support them. For more information about enabling these types of projects or other migration of your assets, see the "Migration report" for details after clicking the "OK" button.

- PROJECT_NAME, "C:\xx\xx\xx\xx\xx\PROJECT_NAME.vcxproj" 

Non-functional changes required

Visual Studio will automatically make non-functional changes for the following projects so that they can open in Visual Studio 2013, Visual Studio 2012, and Visual Studio 2010 SP1. Project behavior will not be affected. - ImageRegistrationEngine, "C: \ xx \ xx \ xx \ xx \ PROJECT_NAME.sln"

EDIT:

The project was created on the same computer using the exact same version of VS.NET ..

By the way, I can still open C # projects, but not C ++.

Answer 1

The accepted answer in this question solved my problem.

Error vs2012: package "visual C ++ package" not loaded

I opened the Developer Command Line for VS2013 and write devenv /Setup (while VS is closed). Then I started VS again, and everything was fine.

Answer 2

The developer command line command for VS2013 is opened in administrator mode and devenv / Setup is executed (while VS is closed). Then VS started working as expected.
