patrican iv

The game should and does run on Windows 10 - I believe you need to uninstall the game from your previous machine thus releasing the product key.
Then reinstalling on new machine should work. - It did for me.

Otherwise you are on to support -
use your existing account to login to the kalypso launcher, then you will be able to play P4.
trying to register the key to a new account wont fit.
