How to determine registered version of MATLAB from a C# program?

I have multiple versions of Matlab installed on my computer. My application needs to be able to determine which is the active or current version of Matlab (ie. the most recently registered version). I know it has something to do with a registry entry. Thanks.

Looks like I got it. Code is kinda rough but it works.

object line;
string registry_key = @"MATLAB.AutoServer";          //@"MATLAB.AutoServer\CurVer";

using (var baseKey = Microsoft.Win32.RegistryKey.OpenBaseKey(RegistryHive.ClassesRoot, RegistryView.Registry64))
{
    using (var key = baseKey.OpenSubKey(registry_key))
    {
        string foo = key.Name;

          string [] bar =  key.GetValueNames();

          using (var subKey = key.OpenSubKey("CurVer"))
          {
              line = subKey.GetValue("");
          }
      }
  }
