Bob,
Then you can duplicate the error in development machine. It wouldn't be as good as tracing a code version but helps.
-Create a folder and put your files there as would be on a client machine.
-Temporarily rename your development folders to something else (so file would not be found from those folders)
-Launch VFP and set defa to your test folder.
-Set path to none (set path to)
Launch your exe with a wrapper code:

On Error Do myHand With ;
  ERROR( ), Message( ), Message(1), Program( ), Lineno( )

Do myApplication.exe

Function myHand
  Lparameters tnErrNo, tcErrMsg, tcCode, tcProgram, tnLineNo
  Local m.lcMessage, lnProgLevel,lcProgStack
  lcProgStack='Program stack :'+Chr(13)
  For lnProgLevel=1 To Program(-1)
    lcProgStack = m.lcProgStack + Chr(13) + Program(m.lnProgLevel)
  Endfor

TEXT to m.lcMessage textmerge noshow
Error #<<tnErrNo>> occurred
At Line <<tnLineNo>> of your Program <<tcProgram>>

Line with error :<<tcCode>>
Error text : <<tcErrMsg>>

<<lcProgStack>>
ENDTEXT
  Messagebox(m.lcMessage)
  On Error
  Cancel
Endproc

It might help you to find out where it occurs at least.
