how to check registry for v8.3 MCR installed using installshield

I have an installshield created msi that installs my program which includes some matlab content. Previously i was using matlab 2010b and installshield was able to check that the MCR was installed by looking here: HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products\92CC873C33664184E88BE53E80548200 and checking that "ProductName" existed. Now that i have switched to 2014a, this no longer seems possible. I don't see an entry in ...\Products\ for anything matlab related. Even the measly programs that i write are listed here.

I can't even seem to get the GUID of anything 2014a related. On the command line i used "wmic product get", which spits out a lot of information on lots of programs (including my programs) but nothing matlab, mathworks, mcr related.

How do i go about detecting the installation of the MCR now???
