thanx Michael, I dont want to install anything during installation of my desktop application. I just want that during installation, installer check that perticular files have been installed or not on the user's local system and prompt to the user that for this desktop application these files must be installed on your system. After prompting this message, installation of my desktop application must be completed. I think you are getting my problem. Please provide help accordingly. I am waiting for your reply.. Plz provide asap... Thanx Deep
