Trying to update iTunes today, and it was moaning it can’t find itunes64.msi in /Local/Temp/IX0001SA/ or something like that. As a result, I couldn’t remove iTunes, update iTunes, repair iTunes just because that file was missing. Lovely.
Trawl through the internet for assistance, Windows Installer CleanUp Utility. This program doesn’t just remove the program from the list of programs installed, it removes the Windows Installer information with it. Once that information has gone, just install iTunes again, and everyone’s happy.
If only iTunes would work now….
