We're in an office and prefer not going computer-to-computer to fix everyone's issue independently, so we had to go via the registry. You can either use the Microsoft FixIt utility to clean up the previous installation for us, or you can edit the registry manually to repair the installation. I've found two ways to remedy the issue in our environment. I'm trying to be detailed so that other folks who run into this issue may feel better about the below fixes being an option for them. There may be other indications, but these are things we ran into. Its value is '1'.' and 'PreventDowngrade. If you run the MSI installation with verbose logging, you may see lines stating: 'PROPERTY CHANGE: Adding BNEWERPRODUCTISINSTALLED property. (now that I know the issue, I'm confident any previous version of the installer will fail). Installing Apple Application Support via the extracted MSI (AppleApplicationSupport.msi) fails with the same error: ' A later version of Apple Application Support is already installed on this computer.' Uninstalling and installing iTunes fails, including via the steps described for a 'full uninstall' as described here on the Apple site (for instance: Troubleshooting issues with iTunes for Windows updates) Please uninstall iTunes, then install iTunes again'.

Apple Application Support is required to run iTunes. When attempting to start iTunes, you may receive popup error 'Apple Application Support was not found. In Event Viewer's Application log, you may see Event ID 1000 from Source Application Error, stating 'Faulting application name: MsiExec.exe' along with a bunch of other error details. In Event Viewer's Application log, you may see Event ID 10005 from Source MsiInstaller, stating the dreaded error message 'A later version of Apple Application Support is already installed on this computer.'

In Programs & Features, there is no Apple Application Support to uninstall. Just some of the symptoms I've noticed in my environment. In other instances, the iTunes installation fails completely with error 1603 (which is generic 'fatal error' code). The installation sometimes appears to be okay, but the Apple Application Support fails to update correctly. The issue occurred for me during the upgrade process from version 11.4.0.18 to version 12.0.1.26 (which is the current version downloadable from Apple). I've been experiencing the same issue as you describe above.
