Gigapixel AI 7.3.0.5b Failes to open from Photoshop

When launching Gigapixel AI 7.3.0.5b from Photoshop I get the message “Cannot open Gigapixel AI - Shared Memory Parms”.

Steps to reproduce issue:

  1. With a TIFF image open in Photoshop
  2. Click on Automate > Gigapixel AI
  3. Dialog opens with error message

This is happening with a single layer image that measures 4680 x 6840 pixels. It happens with more than one image file of this size. Closing Photoshop and restarting it seems to clear the issue for a while. AMD Ryzen Threadripper 3960X, 128 GB RAM, nVidia GeForce RTX 3080 Ti and AMD Radeon Pro WX 2100.

Hi Daniel,

When the error occurs, can you open Windows Powershell and run the following?

Get-Process | Sort-Object -Descending WorkingSet | Select-Object -First 10 -Property Name, ID, WorkingSet

Then, please share the output you are seeing.

If you prefer, please shoot me an email at help@topazlabs.com so we can take a closer look at why this is happening on your machine.
