title: InstallShield: using LaunchAppAndWait() with relative path
body: <p>Suppose, I have the following folders structure:</p>
  
  <p><strong>c:\Test\setup.exe</strong> (this is main installation launcher)</p>
  
  <p><strong>c:\Test\Feature1\setup.exe</strong> (Installation of feature1)</p>
  
  <p><strong>c:\Test\Feature2\setup.exe</strong> (Installation of feature2)</p>
  
  <p>I created customized InstallShield Dialog in main installation launcher where user can click on appropriate button and run Installation of Feature1 or Feature2. I do it using InstallScript <code>LaunchAppAndWait()</code> function. So, my question is - how can I do it using relative paths? </p>
  
  <p>For example:</p>
  
  <pre><code>LaunchAppAndWait("c:\\Test\\Feature1\\setup.exe", "", LAAW_OPTION_WAIT) - it works.
  LaunchAppAndWait("Feature1\\setup.exe", "", LAAW_OPTION_WAIT) - doesn't work.
  </code></pre>
