hiya!
ok, I can always do another restore if all fails.
let's hold off on the restoring just for the moment. restoring over a fresh itunes/QT install can sometimes cause additional grumpiness.
we'll start by making sure the itunes and QT have been scraped out from the PC. then we'll try a careful staged reinstall of QT and itunes.
preliminaries
download and install the Windows Installer CleanUp utility:
Description of the Windows Installer CleanUp Utility
run it and check to see if there's any leftover itunes or QuickTime installation configuration information on the PC. if you find any, remove it with CleanUp.
now use the complete uninstall instructions on the following document as a guide to a removal of any leftover itunes or QT program files:
Trouble installing iPod, iTunes, or QuickTime software in Windows
now download and save fresh copies of the standalone QT and itunes installers to your hard drive. (eventually we'll run the installs from there rather than online.)
Quicktime 7.0.4 Standalone Installer
iTunes 6.0.4.2 Installer
phased reinstall
switch off antivirus and antispyware applications prior to any of the installs
first run the QT 7.0.4 standalone install. reboot the PC.
(if you get an error message on the QT standalone reinstall, let us know what it says. include error message numbers if you're getting any.)
if the QT standalone install went okay, next run the itunes 6.0.4.2 install. reboot the PC.
now try launching itunes. if you get the same error message as before, first check to see if your QuickTime is launching fine or if you're getting an error message when you try to launch it.
keep us posted.
love, b
EDIT: the
very moment after writing this post, i discovered that QTfW 7.1 had been released. so that link to the standalone installer may take you to one of those instead. let's go for that one, it's got security patches in it that QT 7.0.4 doesn't have.
