title: InstallShild custom action arguments
body: <p>I am useing InstallShield Limited Edition for Visual Studio 2010 to create an installer, and I am trying to add an executable custom action.</p>
  
  <p>My custom action in an exe that is installed to the install dir.
  The custom action needs to use another file that is located in the install dir as well.</p>
  
  <p>How do I get the path to the install dir to my exe? I tried to pess [INSTALLDIR] as an argument but it translates to "C:\Program" instead of the correct dir ("C:\Progam Files\MyCompany\MyProduct"). I tried [TARGETDIR] but it translate to E:\ (wrong as well).</p>
  
  <p>Any Ideas?</p>
