The 'ProviderPackage' package did not load correctly

Question

I installed Visual Studio 2012 and at a later date Update 2. After installing Update 2, when I load any project, I get the following error:

Answer 1

I was getting this error on Visual Studio start up:

the 'visual studio component model host package' did not load correctly...

After that bunch of other The '' package did not load correctly... error messages.

I realized I don't have enough free space on my C drive, where the Visual Studio were installed.

I opened up some space and restarted the Visual Studio, solved the problem.

Not sure if it has anything to do with the free space on disk though.
