To start off, I got iTunes 8 within the first few hours it was released and everything was working fine up until now. Last night, I synced my Touch and it turned into an iPhone. It had the sms icon, the phone app, it said "No Service", etc. It looked exactly like an iPhone. After, that it wouldn't show up in iTunes at all. I put it in DFU mode and restored it through iTunes but it still restored as an iPhone. I also tried deleting the old restore file, downloading a new one, and then restoring, but once again it restored as an iPhone. I figured it was a problem with iTunes so I uninstalled it completely and then downloaded the 64 bit file for Vista off of apple.com. During the reinstall, I noticed it rolling back during the part where it was supposed to install Mobile Device Support and at the very end of the install, it says "Windows Installer has stopped working" and crashes. iTunes itself was still installed though, so I opened it up and plugged in my Touch but it popped up and said I didn't have the required software. (Obviously that would be Mobile Device Support that won't install) SOO, I tried reformatting my entire computer. I thought it might be a registry fault or something since iTunes is so hard to get rid of entirely. So after the reformat, before I did anything else, I downloaded 64 bit iTunes and tried to install it, but I got the exact same error. It's like their 64 bit version is broken or something.. I think it might not be affecting too many people because a lot of people got iTunes 8 when it first came out. I don't know... I did notice that it doesn't even run in 64bit. It says "iTunes *32"
