I just got a downloaded copy of Elder Scrolls 3 (my computer sucks so I wasn't going to buy and download 4), and it's in ZIP format, I opened it, it's in .img form, and I want to know what I open it with.

What sort of download? Legal or illegal? If illegal, for shame Venn. Anyway, burning it to a disk should make work if you read it off the disk. Or you could try MagicISO: http://www.magiciso.com/download.htm. I think I've used it before.

Thank you, and legal. I thought I would have to ISO it, but then what do I do to run it? (my problem is I have no discs that can hold a 700mb file)

Please help venn...

Man Venn do any of your electronics work?

There are programs that can extract ISO files. Go to this site and download the trial. Should let you extract the files from an ISO and I think it works for IMG files. Not completely sure it works in the trial, though.

No, I'm always having electronic problems, and I'm trying the thingy now.

More problems! Since it's a downloadable copy I don't know what to do now, because it says I must insert CD rom.

Perhaps DAEMON Tools would be able to mount the CD image in a virtual drive.

Apparently .img files aren't officially "supported", but I have had some luck with them. It's worth a try, I suppose.

I found a crappy knock-off version of daemon tools, because it won't install on my computer, and I've gotten it working and such...
