VS 2012 Crash in Tools/Choose toolbox items

I have taken below error at event viewer. What should I do? Event viewer:

The information is rather insufficient, but according to this source, it seems that 0xc0000005 exception code means "Access is denied", so you can probably try running Visual Studio as administrator.
