I searched for the solutions in google but whatever the solutions suggested havent working for me. There are full permissions for all the folders for the user account which runs this application.Enable both options Run whether user is logged in or not and run with highest priviledges. Also I want to know will this execute in foreground or in the background. In earlier version of OS, I remember this used to run in the foreground rather than the background. Please somebody help me with this. Currently I am running this application by clicking on the batch file daily at specific time .
