Unable to uninstall itunes - network resource that is unavailable
I can't run iTunes. I can't update iTunes. I can't uninstall iTunes.
When I try to uninstall, I get a 'Windows Installer' window that says 'the feature you are trying to use is on a network resource that is unavailable.' The installer/uninstaller is looking for iTunes64.msi.
I am prompted to select from 'Use source:' locations. Selecting either of the 2 options presented results in a secondary alert, "The file 'C:\...\iTunes64.msi' is not a valid installation package for the product iTunes. Try to find the installation package 'iTunes64.msi' in a folder from which you can install iTunes.'
When I search my C drive for that folder and then go through to the prompt but browse to select those locations, I get the same result.
I have tried to download the iTunes install file from Apple.com, but that tells me I need to uninstall iTunes leading me back into the above.
Please help - music collection held hostage.
