ITunes has stopped launching - just nothing happens. A quick google says to delete my temp folder but I can't do this as it says to 'close all applications that might be using it' even when I've got nothing open (other than usual background stuff). If I try to download ITunes from scratch it gets so far then tells me Bonjour won't close and that I need to check I have admin rights (I do) - the only options are to cancel or to try again, trying again just brings up the same message a few minutes later.
Do I need Bonjour? Should I just delete it and try to install it again or will the same thing happen?
Not desperately urgent but I'd quite like to update my iphone and can't... boo...
Thanks in advance if anyone has any advice!
