Hi--thanks for the report!

A few questions to help debug:

1. What's the value of tpai_exe?
2. What happens if you execute tpai.exe from the command line? (e.g., Win + R -> cmd -> paste value from tpai_exe)

[ahosama]

If I execute tpai.exe from cmd, I get this message: Checking if log directory should be pruned. Currently have 10 log files. Log file count is within bounds QObject::moveToThread: Cannot move objects with a parent Logger initialized Error | Attempted to set index out of range: 0 images loaded, but setting index to 0 No valid image files passed

Looks like you do have access to execute tpai.exe, so the error message from the node is indeed puzzling.

Would you confirm the following please?

1. The tpai_exe value within the comfy node points to the file (tpai.exe) and not the directory.
2. The system user that's running comfy is the same user that ran tpai.exe from cmd (can check from Task Manager, under the details tab). Is comfy running on a remote server that doesn't have Topaz Photo AI installed? Is comfy running locally but as a different user with no access to tpai.exe?

If both of these are true, then I'd be at a loss and have to add some more logging to debug.

Believe it or not, I did try to link the exe at first but got an error so I just input the directory only. Now when I include the /tpai.exe, everything seems to work just fine.
