1.Go to http://www.dosbox.com/
and click download.
3.Once you've downloaded the installer, install it.
4.Once it's installed you must run it.
5.Once it's started, type, mount c F:\DISCWLD\
8.You might need to keep Ctrl down and press F12, 6 times.
If F:\ is not a hard-drive. You should move the DISCWLD folder to one.
then change the F:\DISCWLD\ to the new location.
(For example, if you move it to C:\games\ then you type C:\Games\DISCWLD\)
Let me know how it goes.
