When I'm trying to run dosbox, I can get through step two of the basic setup and installation of dosbox. After that, a box appears asking if I want to install the game to drive C. If I select yes, it comes up with an error message that says "cannot access drive." If I say no, then it leads me to a list of drives, all of which the "cannot access drive" messages comes up for.

My computer is a dell inspiron 1520 with Vista, Intel Centrino Duo, 2GB ram.
However, the same exact thing happens with my Dell Dimension 4500 with windows XP SP2, intel pentium 4 and 512MB ram. I'm using dosbox 0.72 and trying to run Goblins 2 and Goblins 3 from CD. (Both games have the same problem, which is why I am not posting in the game specific forum).

I have googled this problem and also read the faq, wiki, and guides board. I apologize if this is posted anywhere else, but I can't seem to find any solutions!
