title: Install4j is bypassing the custom installation steps
body: <p>We have an application packed with install4j.
  The initial step is to choose between typical and custom installations.
  The custom installation is usually bringing up the option to choose the localsettings folder, the appdata folder and in the next step, the installation folder (default: Program Files).</p>
  
  <p>For some reason, in a specific environment, when checking neither of the options, the installation proceeds without asking for the desired folder paths.</p>
  
  <p>An error file was created as well:</p>

  <p>Could you please let me know, what could be the reason for this behavior?</p>
