I wanted to play Hedgewars on an old PC with Windows Vista x64 but the newest game would not work any more. I got an error:
'This application failed to start because it could not find or load the Qt platform plugin "windows" in "".
Available platform plugins are windows.
Reinstalling the application may fix this problem.'
I tried installing version 0.9.25 again but it didn't work.
I read somewhere that installing different versions side-by-side wouldn't make a problem, so I started trying older versions:
Installing version 0.9.24.1 gave the same error.
But after installing 0.9.23 the game worked again.
Could it be that Qt changed something and it doesn't work with Vista any more?
Here I found someone else complaining about the same problem:

But also without a solution.
On https://www.hedgewars.org/node/6923 it is said that Windows XP isn't supported any more. But how about Vista?
