Description

You can create HTTP cookies with one single line of code in your installation script. You may use this to detect from your web pages whether installation of your software product has succeeded.

The Code

System::Call "wininet::InternetSetCookie(t,t,t) (t'http://www.domain.com', t'', \
    t'softwareinstalled = true; expires = Fri, 31-Dec-2004 00:00:00 GMT')"

Using PHP for example you can now easily detect whether your software has already be installed.

<?php 
  if( $_COOKIE['softwareinstalled'] == 'true' ) 
  { echo( 'Software has been successfully installed.' ) }
  else
  { echo( 'Please download and install our software.' ) }
?>
