The solution is not helping me, still we are getting error. Below is the sample code which we are using in our application...

_REPORTOUTPUT  = FULLPATH("REPORTOUTPUT.APP")  && Report output
_REPORTPREVIEW = FULLPATH("REPORTPREVIEW.APP") && Report preview
_REPORTBUILDER = FULLPATH("REPORTBUILDER.APP") && Report Writer.

LOCAL oHtml
DO (_REPORTOUTPUT) WITH 5, oHtml
IF ISNULL(oHtml)
   WAIT WINDOW "Object not found....."
   RETURN
ENDIF
