MPLAB/c18 not creating a .hex file

I was thinking that if no COFF is evident in the directory to be passed to mp2hex.exe, then MPLAB would automatically skip that step or mp2hex.exe would just stop and not display any message.

I encountered this same issue with Smithtown a couple of year's ago and I'm trying to remember how we fixed it. They had played around a lot with the settings and had specified where intermediate directories, etc. were located instead of taking the installation defaults.
It may have been a matter of taking all the defaults or reinstalling MPLAB/C18 to get all the default settings back, but based on your experience of it happening with some files and not others, I suspect we must have recreated the projects as well to correct the project specific settings.

You can run mp2hex.exe from a command line in case it gives you any more useful information.
