WinStars 3

I've uninstalled Winstars 3 from my old Windows 10 computer, and installed the newest version on my Windows 11 computer. Installation goes fine, with no messages about faults. When trying to start Winstars 3, I get a popup telling me that "This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem."
I did, of course, try reinstalling more than once, but to no avail. Everything else is working on the PC, just not Winstars 3.
Have you seen this before, and do you know a solution?

Edit: I just tried a long shot, and installed the 32 bit version. My winstars 3 starts now and works as it is supposed to.

Best regards

Hello and sorry for my slowness to answer you (but as there is almost nobody who comes on this forum, I don't come there often either).
Is your problem still there? I just tried it and I don't see anything wrong.
