I have downloaded the excercise system of the decision management advanced course but it seems to be not recognized by vmware. File name :Marketing_712_VM_20160223. Upon extracting it is creating the below 2 files. I have used zip to extract.
You need VirtualBox to use the exercise system. Detailed instructions to set-up the exercise system is in the Exercise System Quick Start Guide, which is in the same lesson page from where you downloaded the zip file.
