Fresh install, can't install .Net 3.5 sp1 and .Net Family Update

I've been searching for a while most links lead to here. Although I am getting the same error 80070020 I do not have any anti virus installed yet. I literally just finished installing an hour ago and the .net service pack update is the only that keeps failing.

I don't have any .Net framework* in my add/remove programs and like I said I don't have any anti virus programs running yet. I am using a genuine copy of vista (Home Premium 64bit btw) and I am at a loss.

Also, when I select to install it says the progress is at 99%, then it rides, then it fails.

Any help would be appreciated greatly!
