Let me know if it’s working after doing this. If it’s still not working, open Topaz Photo AI, go to the menu bar on the top and click the Help > Open Log Folder menu option. Attach the bottom 3 log files to your reply and I can check what is happening.
Thanks for sending the log. It looks like it’s working from what I see.
Is the application window responding when you make changes?
Please try zooming in to the image further to check if there are any adjustments made. Let me know what you are seeing and I can send next steps once I have a better idea of the situation.
