So, I was instlalling TESIV: Oblivion, everything went smoothly until the end when the installation window froze up. I tried running Oblivion and a message popped up saying it was missing a file, and that re-installing could fix the problem. So, I tried reinstalling Oblivion, but a message pops up: >SetupDLL\SetupDLL.cpp (390) PAPP:Oblivion PVENDOR:Bethesda Softworks (http://www.bethsoft.com) PGUID: a lot of numbers $184.108.40.206844 @Windows XP Service Pack 2 (2600) I click ok, then it says: Setup has experienced an error. Please do the folowing: -Close any running programs -Empty your temporary folder -Check your internet connection Then try to run the Setup again. Error code: -5001 I did everything it said, I put the CD back in, and tried to uninstall, but the same error popped up. Any ideas?
