Patch For Oblivion 1.0.228

For some reason, I cannot install any of the Elder Scrolls 4: Oblivion Patches. It keeps coming up with 'Patch Error - Old file not found, However a file of the same name was found. No update done since file contents do not match'. I've tried reinstalling the game over and over but still doesn't work. I don't know if this is the case, but my Oblivion.EXE and OblivionLauncher files are two different versions. Oblivion.EXE is V 0.1.0.228, while Oblivion Launcher is V 1.0.0.1.
