I got an update on my laptop to install the new version of iTunes, so I tried, but a message popped up saying Bonjour Service failed to start verify that you have sufficient privileges to start system services, so I looked at some online forums and followed directions to delete bonjour services from my computer. I tried to install iTunes again, but the same message popped up. Today I got my new iPhone and synced it to my iTunes on my computer and the same update came up for iTunes 10.5 so i can install the new iPhone 5 software, and when I tried to install it again the message popped up AGAIN and now i'm going crazy. when i looked up services through Run on the start menu i found bonjour services and it said it was disabled but that it was marked for deletion but it won't let me actually delete it and i'm lost. please help!
