Hi, The basic idea to check versioning and download exe is to place your - Installation or exe file - text or xml file which will hold the installation or exe file version to the webserver. Lets assume -> Old Version : 1.0 Latest version : 1.1 To implement this you have to code for an automation service which can check for the latest version from url using webclient, if you find a latest version then download that file to a particular location and run that file through code and the rest of the things setup will do by own means replacement of files. OR The other method is to use any custom service like http://autoupdater.codeplex.com/ Thanks Amninder Singh

Hi So if you don't want to get answer on skype so i am explaining you little bit here. For this you have to store the bit in the database that are you installing the application and you have to place the check on program.cs like if(isInstalling==true) { Validate(); } else { Open Login Form(); } Thanks
