update of Topaz photo AI no longer working with Lightroom classic as plugin

[Darrel Nichols]

I have been using lightroom classic 12.1 with Topaz Photo AI for the past few months without a hitch. I updated Topaz today to 1.1.7 and it no longer works. I followed the instructions in the preferences in lightroom to add the external editior. I browsed to Topaz in the applications folder. I have a mac studio. When I clicked on plug in extras and clicked on process with Topaz Photo AI, from lightroom's menu, it appears to open Topaz as it did in the past but then I get a message of "Failed to process the photo. Topaz Photo AI either failed to start or did not finish successfully."

I can however, open Topaz Photo AI up as a stand alone, and open jpgs on my desktop, but I cannot open files on my disk that are in lightroom catalog using Topaz as a stand alone or through the lighroom plug in. So strange.

I have uninstalled and installed both Topaz Photo AI, and Lighrtoom Classic. Nothing seems to be working. 

I would love suggestions to make it work again.

Thank you,

Darrel

Is the original photo missing in the catalog?

All of my photos are in the catalog. I can go to any of the photos in Lightroom and call them up for development or to look at them when I try to use the plug-in for topaz AI for any of the photos including ones that I took today and uploaded as well as any I took over the last half year I get that same message that Topaz failed to start or did not complete successfully. This seems to be a issue with Lightroom classic since I am able to open Topaz directly and drop any JPEG into it and use its functions. As I have mentioned, I re-pointed Lightroom classic to topaz for the external editor and I can't see what else needs to be done . Thank you for the suggestion. The catalog is up-to-date and everything is easily found.

Here is a screen shot when I try to open a photo directly from Topaz- I point it to my lightrooom catalog:

and here is a photo of what I get when I am in lightroom and try to use the plug in:

What happens if you choose an 8-bit Adobe RGB Tiff?

Also using the Plug-in Extras menu is usually designed for opening Raw files in another app. Does Topaz support DNG? 

[Darrel Nichols]

Sean,  it has accepted the files from LRC (RAW from my R7 which it converts to DNG). Nothing had changed other than the update to 1.1.7. When I uninstalled and reinstalled 1.1.6 everything seem to work again so it seems it is an issue with topaz in the new version.

[Sean McCormack]

At least you have a resolution, albeit not necessarily what you wanted. Thanks for coming back.

I've just updated Photo AI to 1.1.7, and I can sometimes see the same problem....so I definitely think this is a Topaz issue. When using "Edit in...." I'm not seeing any issue, but when using the Plug-in Extras procedure it will sometimes (but not every time) fail with the error that you are seeing. FWIW, proprietary raw files don't seem to cause a problem, but some DNG files (all converted internally by LrC from proprietary raw) do cause the problem. It's odd, because some DNG images from the same camera/shoot will work, but others will fail. But I think it's a Topaz problem with the update.

[Darrel Nichols]

Thank you for sharing. I uninstalled and re-installed version 1.1.6 and everything worked. It seems the problem is with the Topaz update. I hope they fix this.

Hi Darrel, I have had identical problems with Topaz Photo AI and Lightroom Classic. I just tried your fix, of dropping back to the 1.1.6 version, and Presto! Back to where it was working again. Thank you very much for that, I was starting to pull my hair out
