Installed in the same location as? (Error/Conflict)

Hi,
I wasn't sure where to post this problem sorry.
When I go to Uninstall some of my FSX (FS10) aircraft I get an Error:

This error happens with Revo Uninstaller. If I go ahead with the uninstall it deletes all my aircraft in my aircraft folder and all the registry items with those aircraft (I think). If I use Win10 built in Uninstall program it does the same thing but without the warning / error message.

If I remove the Premier 1A Aircraft (with it's own Uninstaller) then a different aircraft will appear in it's place with the same warning / error message next time I try to Uninstall with Revo Uninstaller. There seems to be multiple aircraft doing this when I click Uninstall in Revo Uninstaller.

It seems to be only mainly Aircraft with Installers that are causing the problems.

I just want to be able to Uninstall my Aircraft without losing everything in my Aircraft folder and Registry.

Also

I made a list of all the software that has this "Installed in the same location as" conflict. There are 33 programs.....most are Aircraft for Flight Sim 10 (FSX) both Freeware and Payware affected. The Majority of the Aircraft affected are ones from the Freeware Aircraft / Scenery Rikoooo Installers.

There are some programs like Corel Painter Essentials 6, Intel (R) Network Connections 22.9.16.0, Open Office and Paintshop Pro 2020 that are doing it as well.
Also
With the Aircraft if I use the Aircraft's own installer to uninstall the aircraft it does the same thing wiping all my aircraft's from my FSX Aircraft Folder. I have backups so easily re-installed.

What would cause 2 programs or more to be installed in the same place? Is it a Bug or a Virus? Any ideas on how to to fix this?
