Whenever I try to mount a certain ISO I'm getting the error "Sorry, there was a problem mounting the file" despite the fact that the image mounts perfectly fine using DaemonTools or ImDisk.

File Explorer won't mount files that have the sparse flag set:

fsutil sparse queryflag PATH_TO_ISO
:: => This file is set as sparse

All you need to do is unset the flag:

fsutil sparse setflag PATH_TO_ISO 0
fsutil sparse queryflag PATH_TO_ISO
:: => This file is NOT set as sparse

If you're too lazy to whip out a command prompt, you can simply duplicate the file to clear the flag.
