After updating to Photo AI 1.3.5, I now get the following errors “Topaz Photo AI” is damaged and can’t be opened. You should move it to the Trash". I then get the Photoshop error “Cannot Proceed” Error: plug-in has crashed." Have tried reinstalling several times including your download page and get the same error.
In fact, the 1.3.5 update killed your other Plugins as well, Sharpen AI and Denoise AI. I had to reinstall those as well. They work but not as great as they did prior to the 1.3.5 update.
In the right way, I often uninstall others, and the Windows system has this kind of problem, which can only be solved by copying the 8bf file to the specified path.
