This question was very helpful to me. I came up with a helper class, wanting to play with the new Tuples.

Example usage:

public string SkypeExePath => InstalledApplicationPaths.GetInstalledApplicationPath( "lync.exe" );

The class:

public static class InstalledApplicationPaths
{

   public static string GetInstalledApplicationPath( string shortName )
   {
      var path = GetInstalledApplicationPaths().SingleOrDefault( x => x?.ExectuableName.ToLower() == shortName.ToLower() )?.Path;
      return path;
   }

   public static IEnumerable<(string ExectuableName, string Path)?> GetInstalledApplicationPaths()
   {
      using ( RegistryKey key = Registry.LocalMachine.OpenSubKey( @"Software\Microsoft\Windows\CurrentVersion\App Paths" ) )
      {
         foreach ( var subkeyName in key.GetSubKeyNames() )
         {
            using ( RegistryKey subkey = key.OpenSubKey( subkeyName ) )
            {
               yield return (subkeyName, subkey.GetValue( "" )?.ToString());
            }
         }
      }
   }
