Ok, so I got Arena in my CD drive, go to dosbox, and try to mount it, nothing happens, it says it does not exist.

The Arena is on the CD but is located in OS (C:) Program files (x86) and no matter how many times I try to mount C: it just doesnt work, what do I do to play Arena and Daggerfall?

I am so lost D:

Edit: I am fine with playing them off the disc if there is no other way, but I would love a short cut or something so I don't always have to go through dosbox
