When I launched iTunes (XP,SP3) a "new version" was notified. After a long donload a message appeared along the lines of "ITunes has not been installed because the signature cannot be verified" Any ideas? I think it was version 9.1.2 -not sure.
After advice from iLounge, Opened "Add/Remove programmes", highlighted iTunes, pressed change, then recover. Then the download worked. Often wondered what the change option was for! Maybe it was just a glitch that self corrected.
