It’s not installation issue. I got the same issue on 3 different machines. That annoying “please wait while intellisense and browsing information are updated” pops up and blocks IDE completely even if Intellisense is off.
Everything was fine on 2013.1, there was something similar on 2013.2 on one of the machines once but never came back after reinstall.
I hope 2013.4 will fix it, I didn’t try CTP1 yet though.
