I used to play the game Freelancer, which originally was designed to work with win98/Me/2000/xp, with Windows Xp/Vista/7. Now I upgraded to Win 10 and it doesn't run anymore. The problem is, that it asks for additional rights and tells me to log in again with admin rights, though I have admin rights. I heard, that this is a problem to be expected with older programs, but that you can fix it with compatibility-mode. That's what I have tried so far: • Different compatibility-modes(XP(different SPs)/Vista/7/98/Me) • Run the shortcut with admin-rights • run the.exe with admin-rights • reinstall game • disabling UAC • create a task with the task-scheduler with highest priority • set admin-rights in the shortcut compatibility settings None of this works. I noticed that the game-process starts, when I try to open it without admin-rights, but then I get the 'you need admin-rights' error and it shuts down.
