VS 2012 crashing on start - visual-studio

Question

VS 2012 crashing on start. I assume, it may be as a result of uninstallation of DevX Expression uninstallation which was done through Add/Remove features & Vs still trying to load add-in. Is it?
However I tried removing VS cache file and run devenv/resetsettings and tried VS repair option from Add/Remove featuresbut didn't work. I also tried VS repair option from Add/Remove features Is there any solution to fix the error?
I see two entries in Event Viewer:
Application: devenv.exe
