Page '312e8a59-2712-48a1-863e-0ef4e67961fc' not found using Visual Studio 2012

To fix this, run this from the Visual Studio command prompt as administrator:

devenv /setup

It will not mess up your environment, and you can just continue to use Visual Studio afterwards was my experience.

I had the same error in Visual Studio 2013 and tried:

Control Panel → Programs .... → Visual Studio → Repair

It did not work

devenv /setup

It did not work

devenv /clearcache
devenv /updateconfiguration

It did not work

And then THE solution:

*Close all Visual Studio instances
Delete the %LOCALAPPDATA%\Microsoft\VisualStudio\12.0\ComponentModelCache folder
Start Visual Studio

It is explained in more detail in this blog post: When the EditorPackage does not load correctly

I had this error on Visual Studio 2013 Ultimate - Windows 8:

Team Explorer Error

And I solved this problem running this command:

X64: devenv.exe /resetskippkgs
x86: C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\devenv.exe /resetskippkgs
