Unfortunately this report doesn't add anything new compared to the discussion happened here https://www.qlcplus.org/forum/viewtopic.php?p=73631

What I know so far is that

  1. version 4.13.1 works on several Windows 10 and 11 installations out of the box
  2. removing the ftd2xx64 DLL (which is a dependency of the dmxusb plugin) allows QLC+ to start
  3. the ftd2xx64 DLL was not necessary on 32-bit versions (this actually puzzles me)

To be honest I think the point worth to be investigated the most is number 3
