This is not a big problem but does require one to take the time to go through the process of uninstalling and reinstalling - which, given the size of the program and its models is not insignificant. But, nevertheless, worth it.
Similar problem, but you shouldn’t have to un-install, just use the installer on this site and re-install, it will make use of some of the files on your PC (I think) without downloading everything from scratch.
I still agree its something that needs to be fixed.
Im not impressed by the number of issues with software from Topaz, too many issues for a product we are paying for.
I still cant use video AI, even though my system meets minimum requirements.
Except for a crashing problem I had with with newer versions versions Gigapixel - when up sizing large files 40, 40 in at 300 DPI to 48 z 48 at 300 DPI and the same problem with up sizing with Photo AI - due likely to the fact I that I have an older computer (which I solved by installing an older version of Gigapixel from 2020 - I have had few problems with with the Topaz software and real wouldn’t want to have to live without it.
I find it can achieve nye on near to miraculous results if used adroitly and carefully.
