Program failed with exit code 5

I am trying to use the free app ResChange to set the monitor resolution.  I have made a package with the app in and created a program

"dccmd.exe -width=1440 -height=900 -quiet"

as specified in the app documentation.  If I advertise this to a collection I get a failure with the message

"Program 1440x900 failed with exit code 5"

If I copy the app to the client and run the above cmd line it works fine.

If I set the package to persist in the cache, and then run it from there it works fine

I have also made a batch file with the above command line and tried running that from the ccm cache after it has failed and that works too.  Can anyone help as to what exit code 5 is?
