Install apparently works, but Topaz won't start, no error messages

Hello, I downloaded the free trial of Topaz Video AI, and installed with a success message at the end of the install. Then, when attempting to start Topaz, nothing happens.

I’ve checked the Windows event logs for any messages. I’ve tried starting as Administrator. I’ve tried uninstalling, then reinstalling as Administrator, and then tried to start as Administrator. I’ve tried starting from an (Administrator) command line to see if there was any message that might “flash” to fast to see it. In none of these cases have I seen any info to help me figure out what is going on.

My system: Windows 11, 32GB RAM, AMD Ryzen 9 5900HX, Ethernet connected.

Has anyone seen something like this?


  1. The bug / behavior you have encountered
  2. Your system profile
  3. Your log files (Help > Logging > Get Logs for Support)
  4. Any screenshots as necessary

[Please be sure to have searched for your bug before posting. Duplicate posts will be removed.]

Well, I answered my own question, or at least I found a suggested workaround (not specifically for Topaz, but a general one for programs that have this problem): Disable User Account Control. After I did that, I’m able to launch the application. Not ideal, but it works.

Hi there, this is not normal and should not be necessary.

If this occurs again, please let me know.

Thanks ida.topazlabs - I spoke too soon, I cannot start the program again (consistently, even with UAC turned off), and now one mystery is what was different once yesterday evening, when I was able to start it (just that once so far).

Further digging for clues and diagnostic info found a .dmp in the Topaz AppData folders, and opening that in WinDbg yields the following. (BTW, I am a recently-retired developer, and if you want me to assist debugging / diagnostics on this, I am totally willing to help.) It is an exception in tutils.dll, and although it didn’t look immediately like a missing DLL dependency (which is what my first guess would have been), searching on the exception code 0xe06d7363, I get hits that say it is a missing or damaged C++ redistributable. E.g., this link comes up first on Google 0xe06d7363 Error: Which fix to use? | Windows 11 Forum. Here is the dump info:

Let’s start off with a clean install before we move on to the next troubleshooting step :slight_smile:

  1. Uninstall Topaz Video AI

  2. Delete the AppData > Roaming Folders for Topaz Video AI
    As a note, this folder will be hidden. To view this file, select View > Show Hidden, and here is the path;
    C:\Users<username>\AppData\Roaming\ Topaz Labs LLC\ Topaz Video AI

  3. Delete Registry Entries using the steps below:
    Open program RegEdit from your Start menu explorer and delete the registry entries of Topaz Video AI

I. Computer\HKEY_CURRENT_USER\Software\Topaz Labs LLC\ Topaz Video AI
II. Computer\HKEY_LOCAL_MACHINE\Software\Topaz Labs LLC\Topaz Video AI

  1. Reboot Computer
  2. Reinstall

If that does not work, can you please post your dxdiag?

I see avspmod and virtualdub64 are flagging up the same RADAR_PRE_LEAK_64 error aswell.
Firstly I would suggest turning off any overclocking if you are doing that and secondly run

sfc /scannow from an admin command prompt.

Thanks for the suggestions menditsa. I’d already given sfc a go; no luck. On the overclocking, oddly enough I’ve been unable to figure out if turning overclocking ON is even possible on this new “minis forum” PC (AMD Ryzen 9 5900HX). As I understand it, it has the integrated Vega 8 GPU, but I haven’t found the right utility yet to show me that info (just still getting this device and all the softwares I want set up). This is intended to be my “media hub” for some new AV equipment, and how I’m attempting a major project of digitizing ~250 VHS and ~100 mini DV tapes. I have a rebuilt Panasonic AG1080 for the VHS. I’m currently in the phase of comparing best methods. VirtualDub+QTGMC, hardware upscaling, and Topaz are my major contenders, and of course variations within each. So far, I got Topaz Video AI to run just once. And that’s a very interesting aspect to this problem: what was different that one time? I thought it was turning off UAC that did it, but that was apparently just a coincidence it looks like. How did it get past what I surmise is an initialization routine that once? I surmise it is only during initialization processing that the problem occurs, because when it ran that once, I was able to successfully use it on a couple of test video runs over a period of several hours. I definitely did not put Topaz through its paces yet, but for what I did so far, it had no problems. After I closed Topaz though, then it will no no longer start again, with the same exception during initialization. The exception occurs less than a second after starting the program.

Please do not post hundreds of lines of text, nobody is going to scroll through and read all that. Use the attach file option:


Please delete your previous posts and add the dxdiag.txt as an attachment.

Additionally, post the Topaz logs as they might state why the application is having issues.

They will be located at C:\Users\YOUR_USERNAME\AppData\Roaming\Topaz Labs LLC\Topaz Video AI\logs

And to find out your system GPU, install and run GPU-Z:

Thanks David. I feel foolish for having missed that that was the attachment (upload) button! :^p The GPU is the Cezanne rev. C4. I’ve attached the dxdiag.txt, and also an example of the -Main.tzlog. There are several, and the paired -Out.tzlog in each pair is simply an empty file.

Ok thanks for that, so based on what I see in the logs, you only have an integrated GPU with half a gigabyte of VRAM (which might not even be dedicated memory, it might be shared system memory).

This would not meet the minimum system requirements for video AI:

OK, thanks David. FWIW, the one time I was able to launch the program, I was getting about 4-5 fps upscaling interlaced 480i to 1080P, with a few different filters. I doubt the crash during initialization was performance related, but I suppose if the initialization code is trying to detect HW features that are not there, that could be part of it. Thanks all for your help.

It is possible you may have more VRAM, the problem is that your GPU is showing as unlisted in the profile. Can you uninstall and reinstall the AMD driver and try again?

Occasionally a simply update can fix this for you.

You can download the latest AMD drivers from the following link

There’s no discrete GPU on his machine, it’s an iGPU.

He ran GPU-z and it only reported an integrated GPU. If it’s not on GPU-z, it’s not there.

Also, “ven_1002&dev_1638&subsys_01231002&rev_C” and “Chip type 0x1638” is just the Hardware ID for the integrated Radeon GPU on the CPU, so still just an iGPU.
