I had intended to give away a real classic as a present to a friend running win7.

I have bought worms 2 from a trymedia platform, the game runs nicely with my XP machine.

The game bought and downloaded on my friend's computer opens controls, but does not start the real game giving the message "frontend: Access to an unnamed file was denied."

Is there help? Could there be help from trymedia?

Thanks a lot in advance for your help.

"frontend: Access to an unnamed file was denied."

Are you sure that the directory where you have installed Worms 2 has good writing and reading rights?
