Pushing MSU via GPO based on OS architechture

Hi Pros,

I need to push MSU (KB2459530-v4-x64.msu) via GP. I have found a partial solution here:http://itaudiotech.blogspot.co.uk/2013/05/how-to-deploy-microsoft-hotfixes.html(based onhttp://evilgpo.blogspot.com.au/2012/05/inverting-wmi-filters.html) and WMI filtering based onTino Todino article "Using WMI Filters to apply Group Policy to a target operating system". There is only one thing left for me to do. I need to combine two WMI filters into one: First checks if the patch is installed and the second one to filter the x64 or x86

I am not sure how to combine them.

Thanks
