Windows Installer HELP

Ok. So you guys are my last resort. I've spend hours sorting through forums of all kinds trying to figure this out but anyways, I just turned from linux to windows 7 today and I tried to install my zune software. It first told me that I couldn't do it because the software wasn't ment for 32-bit then I download the software for 64-bit and then it told me I couldn't download that because my windows installer wasn't installed correctly. I went through and tried to delete the reg. key but it didn't even exsist then I tried turning off Customer Experience Improvement Program and still I get the same problem. I wouldn't even care if there was another way just just put music on my zune. PLEASE HELP!
