NIS 2014 start issue

My NIS 2014 starts after boot with about 50/50 chance. Boot protection options don't affect.

OS Windows 8.1, Fast Startup is disabled. NIS version is 21.3.0.12


When nis starts normally, there are 2 instances:

But when it won't start, there is only 1 instance with low memory usage:

And NIS icon don't appears in system tray.

 

After reinstalling Windows problem is still remains. And another computer has this problem too!

What I'm doing wrong?
