Genika works with Basler, not Touptek. Difficult then.

Firecapture... wow... Basler is supported, but does not run... seems to be a common problem when I look into the support forum.

Robin decided against Basler with future version 4.1, therefore I have no hope that even Pylon 6.1.3 (yes, it works) will work in the future.

I never tried Genika Astro. Because it's licence is bounded to three cameras and I am testing a lot of cameras, it is not compatible to my requirements.
