If you have a Mac or Windows with non-NVIDIA 50 series graphic card, you can skip this update.

What were the steps you tried to get this message? Updating through the in-app updater and link above will not show this message.

I also encountered the same error prompt. After upgrading to version 4.0.1 and starting the program, I got this prompt and then nothing happened.

@Uchpa and @wonew - Can you confirm you used the in-app updater to get this error? Lingyu and the development team are looking in to this but when we use the in-app installer on various Windows machines or the direct link, we cannot reproduce on our side. If you have more info let us know! Also test these direct links and let us know what happens:

I received the error after:

  • updating in-app
  • repairing installation
  • uninstalling then reinstalling

Since it seemed to be a test/debug alert, I did not bother to check event viewer for more information.

Reverting back to 4.0.1 works with no issues.

If you trash the other installer, then test this one - Does the direct link to v4.0.2 below work? Not from in app, but clicking this installer?

I was not able to reproduce it. Most likely if you try again it will update you to 4.0.2, although if you don’t have a NVIDIA 50 series device this patch is not needed for you.

I previously tried that but did so again just now as requested. Same result. Checked event viewer this time but there weren’t any relevant log items (aside from the installer completing successfully).

Using NVIDIA RTX 5080

I’m just going to wait until 4.0.3

if you have time, can you send to support@topazlabs.com a screen recording of the behavior updating? I can share it to the development team and Lingyu. If you want to wait until 4.1.0, you can, but if we have not seen the issue or gathered more information, it may still occur.

Welcome to topaz

I believe there is a bug where if you conduct batch proccesing of images on 5070 ti then processing stops at random intervals and does not continue on to the next image

Seeing that your AI Processor settings are forced to NVIDIA in Edit > Preferences > General > AI Processor. Make sure to put this back to the default Auto. It will use both RAM+VRAM, whereas nby being on NVIDIA you are limiting Photo AI from using your RAM. Photo AI will need your full machine capabilities. Keep in mind if you did not change it yourself in Preferences to NVIDIA, it may be the NVIDIA app that did it, if you use ā€œoptimizationā€ option in the NVIDIA app or when you install a NVIDIA driver. Do not use these ā€œoptimizationā€ option for Photo AI in the NVIDIA options, it only changes that AI Processor and limits access to all your machine’s power. To be on Auto, redo a batch and contact support@topazlabs.com if any issues remain!

@Uchpa and @wonew - The development team pushed a fix this morning. When you can test again with the direct link and let us know how that goes!

It was stable recently, but now it’s unstable again😭
I regret the easy update and will now downgrade.

A few minutes ago I almost updated to 4.0.2 from 4.0.1. Fortunately, I read the messages here about problems so I did not do the update.

In-app install of 4.02 completes, Photo AI launches to show in Task Manaager but the app UI never appears. Downloaded the 4.02 .msi file and did a repair and reboot but the app still wouldn’t launch. Using Windows 11 with 64GB RAM and Nvidia Quadro T1000 with 4GB of VRAM. Reverting to 4.01.

@John_smith - can you write to support@topazlabs.com and send us your app’s logs? You can do this from in-app → Get help button. Make sure to attach your Logs and System Profile in that in-app Support Pop-up and we can troubleshoot with you once we get them!

@mbennett60657-779012 - 4GB of VRAM means this computer is under requirements for Photo AI. Send in your System Profile and Logs from here C:\ProgramData\Topaz Labs LLC\Topaz Photo AI\Logs - and we can see if anything possible, however, you may have to stay on a prior version of Photo AI for this underpowered machine. We can know more once we see the logs and driver information.
