VS 2013 Professional - Version 12.0.31101.00 Update 4
All of a sudden, whenever I try to open a project (MVC project or Python project), I get:
Open Command Prompt and use the following commands (if necessary, change the directory according to the installation folder):
Command Prompt
cd c:\ C:\>"C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe" /resetskippkgs"
cd c:\
C:\>"C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe" /resetskippkgs"
Hope this helps...
