i have the same problem on a separate hard rive where i have full access i also double check that i have full access and i run the installation as admin and i still has the same problem, i´m out of ideas what could be the problem and how to solve it, i´m using windows 10, the game worked for a day or two and then it removed it self or such because it said there is missing file and just a short cut ikon on desktop that is not bound to any other file (the main file removed?) also checked my anti virus and fire wall and i can´t see any problems there either
