While the special sale was going, I tried a view of the photo products and noticed they do not uninstall correctly and leave behind their folder.
In detail it was the “Topaz DeNoise AI” and “Topaz Gigapixel AI”, both leaving behind an empty “Logs” folder and hence their own empty folder. Not a big issue, but still, it leaves clutter behind.
In that regard I noticed that every new version of “Topaz Video Enhance AI” produces an entry in the Windows program/uninstall section. I have now multiple uninstalls for this app from multiple versions, but all just upgraded the previous one. Maybe there is a way to work around this for you?
