Been using dos box for a while now been working great the only problem I have run into is installing games from disk when I try to install it says insufficient space.

My system:
Windows 7 64-bit home
i5 processor
8gb ram
Nvidia graphic card
1tb drive

Running dosbox 0.74

Here is what i do

Mount d e:\ -t cdrom
Mount c c:\games\
d:
install
get to install screen and says i do not have enough space it install to c:\daggerfall\

install size is 450mb

the game is Elderscrolls : daggerfalll from orig cd

This just doesn't happen with this game it's with any game were i have to install from disk.

Any help will be greatly appreciated THANK YOU in advance,
