Cannot uninstall/update iTunes on Windows 10

EDIT: iTunes works perfectly other than this one issue. I can still open iTunes, add music and everything else. I just can't uninstall, reinstall or upgrade.

Long story short, Microsoft forced a Windows 10 Fall Creators Update on me, the update was causing my laptop to constantly freeze to reverted to previous version. When I did so, it looked like iTunes had been uninstalled, it shows up like this in my programs list in Control Panel:

When I try to uninstall or update iTunes I get this:

When I click on OK I get the following message: The path 'C:\Users\Josh\AppData\Local\Apple\Apple Software Update\iTunes64.msi' cannot be found. Verify that you have access to this location and try again, or try to find the installation package 'iTunes64.msi' in a folder from which you can install the product iTunes. I tried navigating to that folder but the AppData folder doesn't seem to exist. EDIT: I found it but there's no folder other than Microsoft in it. How do I fix this, if it can be fixed? This has happened to me before but I can't remember how I fixed it.
