If You find it in Registry it means sometime it was registered but somebody can deleted the file :o)))
I thin sure way is to check if You can create an object.

(because I don't know what version of Fox You use this example is universal :o)))

oWord = IsClassRegistered("Word.Application")
IF ISNULL(oWord)
   MessageBox("MS Word is not installed on this computer")
   RETURN
ENDIF
...



FUNCTION IsClassRegistered(cClass)
  LOCAL ret_val, old_error, fl_error
  old_error = ON("ERROR")
  ON ERROR fl_error = .t.
  ret_val = CREATEOBJECT(cClass)
  IF fl_error
     ret_val = NULL
  ENDIF
  ON ERROR &old_error
RETURN ret_val
