Notebook Software and How To Questions

So for a while now I have issues with the HP Support Assistant.

If I remember right there was some mess going up with the Assistant Update because the HP Omen Command Center required a newer version that was just available on the Windows App Store somehow. So I had somehow ended up with two assistants installed on my system, but none of them started.

I tried everything I know to try to get it fixed, but no success. Even was in a state where I couldn't even install any HP Support Assistant version. It always told me that  a newer version was already installed, altough it wasn't.

There was no entry in CLASSES_ROOT/Installer/Products nor in LM\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall.

Somehow got around it my editing the version in the nstallHPSA.exe.config to a higher version. It then uninstalled whatever leftovers. Was then able to install a 8.x version which seems deprecated though, does not show any software updates.

When I try to install a 9.4 .xversion it still complains that  a newer version is installed. That one I can download from the software and drivers section from the hp homepage under my product.

Installing the 9.6.x version works though....but there jus the splash screen pops up for 3 seconds then it closes.

Checked the EventViewer for a log message, but nothing.

Where is HSA checking for installed versions? Searched through the registry and couldn't find any traces related to HSA.

Must be some file in the system?
