Bought game on Steam, want to install form .iso

[Bonfi]

Hey all, I bought Worms Clan Wars on Steam and it's currently in my library but not installed. Now, I happen to have an .iso copy of such game, and since my download speed is very slow (60kb/s at max) I'd like to install the game directly from the .iso instead of downloading it from Steam. Is it possible to do so and having the game linked to Steam with all the features like online multiplayer etc.?

Thank you in advance,

Cheers.

Unless the disk contains a Steam version, the answer is "no".

And since it's an iso and not a disk, even if the retail disks contained Steam games, yours is probably cracked. Unless it's a reasonably precise copy of the original disk with the crack added to it to be applied during installation, even an ".iso" of a Steam game probably can't be fed into Steam.

The data on the cds is not in a useful format that Steam can use to recreate the data. You'll need to download the game via Steam
