Are you sure you cleanly uninstalled Oblivion before reinstalling it? When you ran the OBMM installer, did you use the 'Run as administrator' command from the context menu (right-click)? It definitely sounds like Windows complaining. Try reinstalling OBMM at least.

I did that already before I went and made this thread (uninstalled/reinstalled OBMM and did the right click as administrator thing like 5 times already when it was installed) and I'm still getting that same not working message that keeps popping up! I'm telling you if this not working thing keeps going on then I'm gonna have to either give up playing Oblivion for good or go back to playing Oblivion on my 7 year old slow playing 32 bit Win. PC!
I'm also starting to think that I may have to just erase everything out of my computer (the one this problem with OBMM and other Oblivion utilities) including all of Windows and do a clean re-install of Windows 7, thus erasing out everything on the PC and reinstalling it all over again, which will definitlely take a hired computer nerd to do right!
