Gs _ 99b : this application cannot run under a virtual machine

Maybe try this found from google site

*step by step*
1. Open the start menu in Windows.
2. Search Regedit
3. When regedit is open, open computer, then open HKEY_LOCAL_MACHINE, then open HARDWARE, then open DESCRIPTION, then lastly open System.
4. When System is open, find the file that goes by the name of VideoBiosVersion.
5. Delete the content inside VideoBiosVersion.
6. Close regedit, re-open the game that didn't work before (You may have to re-do these steps every time you restart your computer),
