Can I assume it is still safe to proceed?

I've used it with Win-10, as well as Win-11 with no issues, but just the free versions.

However, I'm not sure the paid version will offer anything more than the free version does for what you're trying to do. It offers more features, but it sounds like you're just trying to uninstall one program for the most part.

Another option might be to press Win + I to open the Settings window, and navigate to Apps > Apps & Features. Scroll down the list and see if PDF Suite 20 is on the list. If so, click it and there should be an option to uninstall.

Sounds like that's already been tried ...

Yup, missed it, thanks.
