I tried to download the Arena game from the Elderscrolls website and put it on a disk. My desktop computer has no network card so I had to use a laptop and copy the file to a burnable disk. When installing it on my desktop the installer says that a file is corrupt and that I can put in a code "/NRC" in the Command line any ideas???
Thanx.

Were you able to run it on the laptop? It may be a corrupted download

No didn't try that. Also the laptops OS is Vista the desktop is XP Pro could that be the problem?

It shouldn't, not that I know of, no.

properly just a corupt download, re-download and try again.

I can assure you that it is not Vista, XP or any OS related problem. I've also played it on Linux without any problems. Just do what da mage said.
