Hi. I just wanted to let you guys know what I found out about this issue. I have worked and worked to resolve this problem which started after I upgraded my iTunes. I tried everything mentioned in all of these posts and nothing helped.
I concluded that the problem is caused by an issue in iTunes 8.0 and above and there is no way to correct it until the problem is fixed by Apple and a newer version of iTunes is released.
Finally, here is what I did:
I went to the Programs and Features control panel and used it to uninstall Bonjour service, iTunes and Quicktime. You have to restart after each program is removed.
Once that is done, go to
http://www.oldapps.com/download.php?oldappsid=iTunesSetup7629.exe and download iTunes 7.629. This is the immediate predecessor to iTunes 8.
After download completes, run the installer and make sure that it installs QuickTime as well as iTunes. Bonjour service is also installed with this same installer.
Restart the computer and after it reboots, iTunes will work fine. Bonjour service will be running and if you have other computers running iTunes on your network you will now be able to see the other computers' iTunes libraries. This was another issue in iTunes 8 in which the other computers' iTunes would show up but you would get an error when trying to open their libraries.
I have Windows Vista Ultimate 32bit and everything works great after I downgraded to 7.629.
That's my solution. I will upgrade only when Apple addresses this issue and corrects the problems.
Let me know if questions.
