Installing SolidWorks through SCCM 2012

I want to deploy SolidWorks 2012 SP 2.0 x64 using SCCM 2012. I have searched nearly entire documentation around SolidWorks deployment but couldn’t get a straight resolution. Found https://forum.solidworks.com/thread/58846 but steps in last post are not clear. I have created the administrative image but how do I convert it into MST? It is proving to be a curveball for me so any help will be deeply appreciated.
