Help! Can't figure out what is wrong

[Nucholza]

So I haven't touched or logged into WoW since last December and when I tried to patch I kept getting an error along the lines of "Failed to patch try again later". So I decided to just download the patch from a mirror and when I double-click on it to install it does nothing - won't launch and the little windows circle thinking thing goes for a second and stops. I tried launching the game and it then starts the blizzard downloader and recognizes that I have the patch already and fills up the downloead bar in a few seconds and then when it goes on to the install step same shit - nothing happens.

So I decided to just uninstall WoW and when I move out in a few hours and go home I'll reinstall fresh (or try to). I'm worried that when I try to reinstall nothing will happen once again because....

I downloaded the SC 2 beta last night and when I run the installer its the same thing as WoW - nothing happens at all. Windows 7 prompts me with the whole "do you want to allow this program to make changes" and then nothing will happen.

Any idea why this might be happening? Starting to look like I might have to completely reinstall windows.....sigh.
