I have been looking everywhere to figure out how to add my new Topaz Denoise AI and SharpenAI to Photoshop 2021 v22.1.1 plugins. The instructions I find all say go to Preferences - Plugins- "Check the "Additional Plugins Folder" box to accept new files." The problem is I have no such Additional Plugins Folder box. Anyone got any suggestions? Would really appreciate any help.
