I recently got oblivion from a friend who was uninstalling his copy (too many hours "wasted"). I got the game from him and tried to play it on my laptop. I the folders there was no install application and it seems like the game is in an installed state. However it will not, screen goes black as if to play the titles, then straight back to windows home.
I wanted to do a reinstall to see if that could fix the issue but even the uninstall program will not run. Gives a .DLL error.
Any ideas what I could do to get up and running?

I find when I can't get game or software to uninstall what I do (which may not be the best way to do it ^^;) is start my pc in safe mode and just manually go to the file location and deleted everything
