Itunes wont open after an update from Apple.

Many people have been having the same problems this week because of he update. Someone on the forum mentioned uninstalling "Bonjour". +Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network - Wikipedia.+ If you have never needed it uninstall it. You could also try typing "MSCONFIG" in the Run selection under the accessories folder and un-checking it under the "Services" tab.

I personally have had the same problems. What i did was i un-checked it on the MSCONFIG menu first and then uninstalled Bonjour.

Hope all this helps

It was definitely Bonjour that has caused this problem. It has taken me days to find out why suddenly I can't open Itunes after an Apple update. I found this thread. Removed Bonjour and now all is fine.
