This is a known problem with the Studio 2.0.11 version that is awaiting a resolution from the developers.
Note: I just checked and I can no longer open DeNoiseAI in stand-alone or plugin mode so something is quite hosed at the moment. And apparently the Studio v2.0.11 messed up my SharpenAI installation as well. I had to reinstall both of them to get them working again.
Hi, As mentioned it is a known problem and the only workaround I have found myself is to remove the three plugins from the Topaz Studio folders:
Remove the following 3 plugins from the “-diskid-:\Program Files\Topaz Labs\Topaz Studio 2\PS_Plugins” folder … tltopazadjustaips.8bf, tltopazdenoiseaips.8bf and tltopazsharpenaips.8bf
Remove the following 3 plugins from the “-diskid-:\Program Files\Topaz Labs\Topaz Studio 2\PS_Plugins_x64” folder … tltopazadjustaips_x64.8bf, tltopazdenoiseaips_x64.8bf and tltopazsharpenaips_x64.8bf
This will mean that DeNoise AI, Sharpen AI and Adjust AI will be available in PS but but not through Studio 2.
The issue is caused by “ghost” plugins because the architecture has changed and Topaz have taken to provide a link that addresses the whole of the upper level Topaz Program folders thereby finding 2 of these plugin entries, one in the program file folder and the other in the Studio 2 folder.
That would be a false positive if the installer for gigapixel is from the Topaz Download site.
