PTXprint 1.9.3 doesn't run on Windows 10 21H1 (build 19043.1110)

PTXprint 1.9.3 installs, but when launched, returns the error “Fatal error detected. Failed to execute script ptxprint”, so I don’t actually get ‘inside’ PTXprint.

I had the same results with a few previous releases.

Thanks Murray for letting us know. You’re not the first one, so at least you’re not alone. However, we’re stumped as to what might be causing this. If you are willing to help us diagnose this problem, I can send you a link to a beta test version of 1.9.4 which will also include a “terminal” window with any background error messages. This should help us figure out what’s wrong. If you are willing, then please send me a private message, or an e-mail to and I’ll send you a link within the next couple of hours. Thanks!
