    Hello guys, can you please help me?
    I’m on a macbook, installed Parallels (trial version), and from ubisoft I bought Might & Magic Heroes VII, when I click on Play button in Ubisoft Connect, it seems that the game is about to launch, I see some loading messages like “Synchronizing saved games with cloud” and others, but after couple of seconds this window disappears and nothing happens. I also can’t find mmh7game-win64-shipping.exe file in downloaded game folder, it doesn’t exist

    Po dokončení nabídky (Opera prohlížeč – pouze možnost stažení) stahování nezačalo.
    Nabídka Fortnight Season 2 mi nebere tel. číslo.
    A poslední možnost je průvodce FIFA 22 a toho neotřebuji, tudíž nemám nutkání zkoušet tuto možnost.
