title: WIX check if VS2015 C++ redistributable is installed
body: <p>Does anybody know how to check in a WIX project, if the actuall C++ redistributable package is installed or not? This <a href="https://stackoverflow.com/questions/12206314/detect-if-visual-c-redistributable-for-visual-studio-2012-is-installed">link</a> describes the serveral product IDs, but there is a problem with them. They change with every update of a C++ redist package. Based on that I've to apapt my checks in the WIX project every time a new VC redist package update is released, which is not a useable solution.</p>
  
  <p>I want to use the <code>RegistrySearch</code> WIX element to solve this problem. Therefore I need to know a registry key that doesn't change if a newer version of a C++ redist package is installed. I've also checked the registry key described in this <a href="https://stackoverflow.com/questions/12206314/detect-if-visual-c-redistributable-for-visual-studio-2012-is-installed">link</a>, but no one seems to be reliable.</p>
