Ok, I managed to install Workstation 10 correctly.
Now I have the next problem. I have installed windows 8, but it is horrendously slow sometimes. Also Windows 8 froze down completely during installing of windows updates. It also slowed down my host OS.
Now i've restarted both host and guest OS, and I get these errors every time:
What is going on?? This version of Workstation seems bugged as hell to me.
Edit: I guess my guest OS is completely dead now?
