technically its not even on my computer, its on a disk, it says the disk isnt a valid win32 app., cant do thier add or remove method cuss its not even installed
Edit: ive updated my firmware, adn then tried, gave me the same error
Final Edit: ive found the reason why oblivion wouldnt work, Microsoft anti piracy software on the disk automaticaly stop you from using it if you have any cd coping software (mainly nero and its incd4), you have to uninstall these softwares to use them, the restart your computer.
No its not Microsoft here. Oblivion actually is great since it only checks the DVD (no securerom or starforce). I think INCD might have been blocking it in your case. No need to uninstall Nero just remove INCD4
