I open the Oblivion_v1.2UK.exe and it starts to download the new patch to my Oblivion folder, but when it starts to process oblivion.exe I get patch error and message ''Failure Renaming/Deleting File D:\Oblivion\Oblivion.exe
Because of this error, I can't download OBSE ---> needs oblivion patch v1.2.0416.
So, what should I do, I'm totally confused because I have cd version of the game and I'm using Windows XP.
