Imgmount needs to be specified whenever you close/open DOSBox unless you place the command in the autoexec section of DOSBox.conf

If your program doesn't need the CD when you run it then you'll only need to mount the CD when you install.

Thanks for that. The prog calls for the CD when it runs, so I didn't want to be bothered with it, hence the creation of the ISO. Actually, it's since occurred to me that I'm probably only going to need to access the ISO once anyway, to do the install (using its 'install.exe' file) then after that I'm assuming it'll create a new sub-folder somewhere else to run from in day-to-day use. Al least that's what it does on a DOS computer. It creates a folder called F2B then on subsequent uses it looks there, as well as on the CD.

But it was the imgmount process that was baffling; it kept telling me something to the effect that 'I wasn't telling it where to put it'. Sorry to be vague, I'm just working from memory.

Perhaps you'd be kind enough to tell me what my imgmount command line should be, given the parameters and locations I used (in my first post)?

Thanks.

Use of the imgmount command can be thought of as equivalent to sticking a physical CD-ROM into a real DOS computer, except that under the hood DOSBox is really reading from an image file (ISO/BIN-CUE/whatever).

imgmount works just like the mount command, except that instead of giving it a path to mount to a drive letter, you give it the path and filename of the CD-ROM image file (note that the path should be relative to the host's filesystem, not the virtual one inside of DOSBox).
