Unable to update AIP Client with Intune

uptocloudlimited I've had this issue for years, and reported if via support cases, and directly to PMs for AIP, and it's never really been understood or fixed... apparently it's just me, although I've rebuilt my machine and it still does the same... and it's good to finally meet someone else it happens to.

For me when I want to upgrade I have to uninstall AIP, install an old version that doesn't have the issue (2.0.778.0), and then upgrade that old version to the new/upgrade version, which works every time... until the next new version and I have to do the same again.

If you look through the logs enough you'll probably find "The File 'adxregistrator.exe' is not marked for installation" - which I think for us once when I looked really hard, was some issue with Excel and "Add-In-Express" (i.e. adxregistrator.exe), but I never could solve it.
