Well... I can't install game. :)) And that's all.

I spent four hours of waiting but installer is stuck at 80% or 90% (look at picture).

Anyone got same problem?

Did you get it figured out?

If still having problems, try installing with Galaxy. I had the same issue with standalone installer at release, but installing via Galaxy made it go without issues.

well, four hours just isn't enough. :)
I just waited and waited and game finally installed successfully.

That's insanely long, but good that it worked out in the end.
Happy gaming!
