Ok, so my guess is that you have a PATH problem. You could check something of the kind:

IF FILE("MyHelp.chm")
   SET HELP TO MyHelp.chm
ELSE
   WAIT WINDOW "Help not available..."
ENDIF

>>Is CHM file type registered in the target machine? If you double-click the .chm file does it fire the help browser?
>>
>>>I have a chm help file with my vfp6 application which runs from the application no problem on my machine where VFP is installed, but when I run my application runtime on a machine without VFP installed nothing happens.
>>

>The help file will run with no problems when you run it outside VFP.
