WoW manually patching problem, please help?

Hello

So i wanted to patch my wow to 3.3.5a so i uninstalled wow and now its version 3.1.0 , so i downloaded a patch from 3.x.x to 3.2.0 which was 1.6GB. Now when i try launching this nothing happens -.-. No error not anything just when i click a bunch of times it makes Installer.exe in processes and nothing else. PLEASE HELP :(

This is how it looks, the file with the red circle around it is the patch.

I had to do it yesterday due to my Hard drive messing up on me. I just let it download when I was sleeping so when I got up all 16GB had downloaded. That is the only thing I can think for you to do, sucks I know.

Hope this helps

x)|||well thanks but is there any other way? :/|||Maybe you could restore your system to an earlier date, therefore putting wow back the way it was before you uninstalled it|||Why do you want to go back to patch 3.3.5a? the onyl reason I can think of is if your wanting to play on a private server, in which case its against the Terms and conditions of playing wow, therefore not allowed to be discussed here.
