iTunes won't run
My son installed the update on iTunes, and now iTunes will not run. He's using Windows 7. I'm not sure the version of the update, because obviously I cannot check it, but I'm pretty sure it was at least iTunes 10.
When I try to open the program, I get the message, "iTunes cannot run because some of its required files are missing. Please reinstall iTunes."
I have tried to uninstall iTunes, and it says, "The feature you are trying to use is on a network resource that is unavailable."
I have tried to just download iTunes and install again, and I get, "The installation source for this product is not available. Verify that the source exists and that you can access it."
I've read on this board about a previous problem like this, and it says to use the Windows Installer Cleanup Utility. That utility is no longer available on the Microsoft site.
He cannot use his iTunes now, and it's really frustrating.
Can anyone help me fix this?
Thank you!
