A few days ago I opened VS2012 just like I do every day and after getting the page where you select the project to open, VS2012 crashed. Restarting the computer, getting all latest Windows updates and playing with registry values did not help at all. See below for answer on how to fix this issue.
It turns out the problem is Internet Explorer 11. It turns out that installing IE11 is what caused VS2012 to crash and be useless. This will fix the issue:
You need to re-register ieproxy.dll - after this VS2012 started to work again.
32 bit systems:
regsvr ieproxy.dll
64 bit systems:
regsvr32 ieproxy.dll
