visual studio 2012 incompatiblity and editor package not loading correctly?

Question

I used to use vs 2012 for some month without any problem, today when I want to open my c# project , I got this error message:

This program has known compatibility issues

Visual Studio 2012 Express for Windows Desktop is incompatible with this version of Windows.

when I click Run program I got this error:

'Microsoft.VisualStudio.Editor.Implementation.EditorPackage' package did not load correctly

When I continue with this error message, another error message shows: Visual Studio has stopped working. I need to get it work as soon as posible, any idea?

thanks for editing, but I need the answer more! ( just kidding ) — Narges, Jul 17 '13 at 19:36

I just got this error in VS2013 after installing a VS extension. I fixed it by closing all instances of Visual Studio, then removing %LOCALAPPDATA%\Microsoft\VisualStudio\12.0\ComponentModelCache

Confirmed still working (for a problem randomly cropping up in 2014!). This was not after installing a new extension though, just seemed to occur out of nowhere. – Nicholi May 20 '14 at 18:55
Same here. I disabled a random extension and restarted, that also fixed it for me. I could enable it afterwards again. – Ray Aug 13 '14 at 08:20

Happened to me today on VS 2012. The Update mentioned by Jarek didn't install (it complained I already have more stuff installed). Deleting the folder mentioned by squeaky didn't work.

Finally fixed after I installed VS 2012 Update 4 : http://www.microsoft.com/en-us/download/details.aspx?id=39305
