Mount FAT disk image file (.img) that PowerShell can't open?

[emendelson]

I'm working on a script that uses image files (.img) in the FAT format, created by the IMGMAKE command in the DOSBox-X DOS emulator. PowerShell won't mount these files; I can open them in WinImage, but I'm trying to find a way to mount them as a drive letter in Windows so that I can copy or delete files on the image.

Is there a way to do this through AutoIt?  The closest thing I can find is the ImDisk driver, but it needs to be installed in Windows, and I want this script to be usable on other people's systems.

Thanks for any help.
