Unable to install / repair neuroserver - Download points to HTTP instead of HTTPS and does not start

d.raebiger · June 19, 2026, 6:57pm

Hi there,

I am trying to re-install / repair after the initial Update to 1.6.1 failed to install

Any ideas ?

Edit:

Trying to download http://video-models-blue.topazlabs.com/neuroserver/20260601.1/windows/neuroserver-deps.tar.xz from my browser works just fine.

running the install msi from an elevated promt does not help

The neuroserver json file is odd:

notice that this is NOT httpS but only insecure http

Thank you for sharing the screenshots for this situation. If you launch the installer again and choose Repair, it should complete for you.

I will check with the team further on the URL issue to see what they say.

Thanks, but this error happens both with a fresh install and repair mode. Initial update failed as well.

kyle.topazlabs · June 23, 2026, 5:04pm

Are you able to pull the installer log from the system and send in for review?

The app should have generated one and stored it in the following file path: C:\Users\Owner\AppData\Roaming\Topaz Labs LLC\Topaz Video\logs

Still unable to install/repair. When will this be fixed? i cannot use the software right now due to this.

johan.tavernier · June 29, 2026, 6:10pm

Same problem here with version 1.6.1 installation. Looks like this problem has been there for a while (since version 1.4) and HTTPS does not help!

johan.tavernier · July 2, 2026, 4:34pm

Well, I managed to get this working:

You need to download the neuroserver containers from the Topaz servers first: https://video-models.topazlabs.com/neuroserver/20260601.1/windows/neuroserver-deps.tar.xz and https://video-models.topazlabs.com/neuroserver/20260601.1/windows/neuroserver.tar.xz
extract both files in a folder called “neuroserver”. You will get some duplicate files warnings but you can ignore those.
install Topaz Video and press OK when you get the “Unable to install neuroserver” message
Don’t start Topaz Video just yet
Move the “neuroserver” folder (and its content) to your “Program Files\Topaz Labs LLC\Topaz Video” folder
Start Topaz Video.
You should see the Starlight enhancements appear in the right column.

Hope this helps for you too!

Thanks, this is working Awesome job!

Nevertheless, Topaz really needs to fix this!!

d.raebiger · July 13, 2026, 12:49pm

It’s been nearly a MONTH without a solution for a product I am paying for.

Please note that I am highly dissappointed.

kyle.topazlabs · July 13, 2026, 5:44pm

The team is actively working on this situation, but it is taking longer than anticipated.

Did the steps that Johan shared above work, or has the problem returned?
