title: Run batch file in Windows Installer Commit
body: <p>I am having no success in modifying a Windows Installer MSI to run a batch file after the primary output has been installed. I have searched for this and found many suggestions, but nothing that works.</p>
  
  <dl>
  <dt><b>Add a Custom Action</b></dt>
  <dd>Custom actions can only be executable files. A batch file is not executable.</dd>
  <br/>
  <dt><b>Create a Windows Scripting Host executable that runs the batch file</b></dt>
  <dd>Many people have tried to do this, including on <a href="https://stackoverflow.com/questions/98778/">SO</a>, and no one has been able to get this to work.</dd>
  <br/>
  <dt><b>Use WIX or InstallShield</b></dt>
  <dd>I do not have the time or authority to change company installer technology.</dd>
  <br/>
  <dt><b>Edit the .msi with Orca and add a custom property, then a custom action, then edit the InstallExecuteSequence, ...</b></dt>
  <dd>I have been trying this for hours and have only created installers that throw a system error when I run them.</dd>
