title: Batch file can't immediately see environment variables created by InstallShield script
body: <p>We use <em>InstallShield 2008</em> for our product installation. Product consists of several components. When a component is installed, a batch-file with some post-install routines specific to this component is executed.</p>
  
  <p>The problem: post-install batch files use some environment variables that are set during the installation of the product through <em>InstallScript</em>. But it seems that batch-files can't see immediate changes in registry (and newly created environment variables).</p>
  
  <p>Is there a way to accomplish installation without a system reboot?</p>
  
  <p>Potentially useful information: target system - <em>Windows XP</em>, currently logged in user is in <em>Administrators</em> group.</p>
