A friend of mine is trying to reinstall a game and they run into an issue where the computer says it can't install it since it's already installed. This, however, isn't true. The program was uninstalled from Add/Remove Programs, the program files were deleted, and the related registry keys found were deleted. Rebooting after that results in the same error.
Does anyone have an idea about how to go about fixing this besides reformatting? Or perhaps a workaround even if it's not perfect?
the only thing i found was something about a dude having the american version and then trying to install a english european version (I assume after uninstalling american version or for some upgrade idk).
