How to prevent program running as an Administrator?

I have this very old piece of software than runs itself as an Administrator; a fact that I can see under the

Task Manager > Details > Elevated

And apparently this causes problems with some other programs trying to cooperate with it

So my question is: how do I stop this software from being elevated?

I have tried going to its EXE and turning for it ON & OFF the

Properties > Compatibility > Settings > Run this program as an administrator

option, but it did not reset the EXE. Also renaming the EXE did not full the operating system

I am using Windows 10 Enterprise 20H2 19042.746

Perhaps this helps:
