Issues with mutiple models? If issues occur with any other models, you can test steps here first. Then if Remove issues remain only, this file below should fix any remaining issues.

Step 1: Install the Latest Version

If not on v1.6.0 already - Install v1.6.0 from your Apps Page

Download JSON file

Important: Ensure the file name in your Downloads folder remains exactly: sdi_unet_nogpu.json - The file name cannot include: (1) or (2) or any additional numbers. If Windows automatically renames the file, rename it back before proceeding.

Step 4: Replace SDI file

Copy and paste the following path directly into File Explorer:
C:\ProgramData\Topaz Labs LLC\Topaz Photo\models

The copy and paste step in File Explorer is important as the ProgramData folder is hidden by default on your machine. To un-hide it: File Explorer Folder Options → View → Enable “Show hidden files, folders, and drives” → Click Apply and OK.

Once in the \Models folder, place the new: sdi_unet_nogpu.json file you downloaded into the Models folder.

If prompted to replace an existing file, choose Replace.

Then, open the app and go to Edit > Preferences > General > AI Processor > Auto. It is important to be on the Auto option to use your full machine capabilities (CPU+GPU).
Retest Remove Tool in the app.
