ITunes 10.4 update fails with error "A program required for this install to complete could not be run."
Completely removing iTunes, QT, etc. made no difference. Win7 32 bit SP1, Home Premium. My user account is Administrator; running the installer "as Administrator" (r-click..) also fails. The error text is less than helpful... anyone else seen this one?
