I just got an iphone and cannot set up my itunes. i get the message "The feature you are tying to use is on a network resource that is unavailable. Click OK to try again, or enter an alternate path to a folder containing the installation package 'itunes.msi' in the box below.
I then get a message that a previous version of itunes cannot be removed. When I try to uninstall itunes useing windows installer I get the same message. I'm using Windows XP. SERPCK2

I've tried the solution on apple.com, and still no luck. I've searched my computer for *.msi, and the two files they directed me to don't actually exist. I tried to install itunes again, but no luck. It still wants to search the temp tiles for itunes.msi.

I "upgraded to iTunes 7.7 on my PC and it bombed not only the old version that worked but the new installed version as well. I hope Apple don't wait another 6 months to reply. I get a message 1603 which indicates the old version wasn't removed properly. How do you do that?
