title: Building Wix on Visual Studio Online results in 'incorrectly registered scripting engine'
body: <p>I recently decided to try out visual studio online to automate my build. The build result should be some binaries and a wix created installer. Locally this works, however on visual studio online this results to errors:</p>
  <blockquote>
  <p>light.exe: Error executing ICE action 'ICE01'. The most common cause of this kind of ICE failure is an incorrectly registered scripting engine. See <a href="http://wix.sourceforge.net/faq.html#Error217" rel="noreferrer">http://wix.sourceforge.net/faq.html#Error217</a> for details and how to solve this problem. The following string format was not expected by the external UI message logger: &quot;The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance.&quot;.</p>
  <p>[..]</p>
  <p>light.exe: An unexpected Win32 exception with error code 0x643 occurred: Action - 'ICE09' Fatal error during installation</p>
  </blockquote>
  <p>The only solution I know to solve this is to give the build server administrator rights. In this case this is not possible.</p>
  <p>Does anyone know if it is possible to use Wix on Visual Studio Online? If yes, what do I need to change?</p>
