Although MT and Studio are installed on my machine. I seem to be unable to connect the relevant addins. I have Passolo 2015 and MT/Studio 2015. Also, when I click on Setup... - nothing happens.
Message for MT:

No supported SDL MultiTerm version is installed on this machine

Message for Studio:

Please install SDL Trados Studio software to use "SDL Trados Studio" addin. If it is already installed, provide the installation directory on addin's settings .xml file

What exactly to I have to enter in this xml? In the first InstallLocation or in both?
<?xml version="1.0" encoding="utf-8" ?>
<TradosStudioSettings>  
  <!-- If Passolo does not find the Trados Studio installation path you can enter it here -->
  <InstallLocation></InstallLocation>
</TradosStudioSettings>
