Just a quick update that this issue remains: as of right now non-cuda (cpu) image generation is broken, however I have fixed the issue locally. I need to run through a series of tests, most likely make some more tweaks and will push a new build tomorrow. We operate out of Colorado in the United States. I will likely have the fix pushed by tomorrow evening at the latest.
Furthermore I can confirm (via yet another completely clean windows machine) that the .NET Desktop 6.0.9 x64 architecture is indeed deployed and installed properly if you use setup.exe NOT the msi file as instructed earlier.
On the other hand, on a different PC DID have the .NET runtime installed, I had to use the msi installer to achieve a successful installation as stated earlier today.
It would seem that the best bet is to use setup.exe, and use the msi installer failing that.
Once non-cuda image generation has been fixed I will list the product for sale once more.
