At the moment I have very limited account privileges, is this the reason why it doesn’t start?
Also I’ve tried diagnostic tool, but it doesn’t start for the same reason!
Sorry, I figured it out, it can be closed now. 
What was the solution?
Simply restarting Windows! (I had a VERY limited account that time)
What was the reason you had limited account privileges? Was that caused by your system administrator/Windows settings or by CIS?
I think it was a Windows problem, that time it didn’t started properly…at least as far as I know.
