Hello,
(my English wasn't really good sry for that:confused:)
If I start Worms 4, it comes the Message: "Would you like to restart your computer to install the Copyright-Drivers?" If I press Yes, the PC restarts. I start then Worms 4 again and it comes the same. Can I install the drivers manually?

thx

Are you on win7/vista? Try running the game, or the required app, as an Administrator (Right click - Run as Administrator). Probably the game fails to install driver because of lacking priviledges

No, the this wasn't the Problem. if I start Worms not as Administrator, the Game sais, that I have to start it with Admi-Rights again. So this wasn't the Problem. (I work with win7)

Which version of Windows are you running? Unfortunately the DRM used in this game is incompatible with Windows Vista or higher...

Its ok, i've download a crack and it happens;)
