After bought and played Skyrim for half a year, I decided to also buy Oblivion to play. Went out and bought the "5th Anniversary Edition" package with the expansions included.

Now trying to install it but it stops right after clicking in which map to install.

It comes with a "feature transfer error" pop-up with in it:

Feature: DefaultFeature
Component: DefaultComponent
File:
Error: Acces is denied.



I run Windows 7.

Please help. I so love to play this game.
