After installing TOPAZ Video AI 3.0, VEAI 2.6.4 crashes on launch

Hello all,

I was working on a batch of videos yesterday and saw that there was an update available (via red icon on Logo)

I installed the update, and didn’t uninstall VEAI (when given the option at the end of the installer)

I was trying out VAI 3.0.0, but noticed a few missing options from VEAI (noise size & amount) etc. etc. but also had one video that wouldn’t import.

I decided to open up 2.6.4 to finish my queue before using 3.0.0 any further, but 2.6.5 now crashes shortly after the main window displays.

I’ve tried uninstalling both 3.0.0 and 2.6.4, deleting temporary files (%appdata%/%temp% etc), cleaning registry.

After fully removing both software and installing 2.6.4, I can get it to launch.
It will sit there open, as long as I want it to, as soon as I log in, it authenticates my details and crashes instantly.

After that, any subsequent launch also instantly crashes

No hardware changes have been made to my PC at all or other changes aside 3.0.0
Any ideas?
