Dell Command | Update has been detected, Dell Command | Update cannot be installed

So, it's funny that this software seems to be unaware of ways to simply update itself when starting the installer.

I have tried to uninstall "Dell Command | Update", but that uninstall process was interrupted. Now I have a system, "Dell Command | Update" is not in the list of installed programs, but "Dell Command | Update" still thinks it's installed.

I already found the installation folder and deleted it - I also searched the registry for "Dell Command | Update" and deleted all I can find about it - but still the installer tells me that it's there.

How does the installer detect an old version? Can I delete something else, so that I don't have wipe and reinstall Windows?

Forgot to include my system info:

• Precision 3571
• Windows 11 Enterprise 22H2
• Build 22621.1413
