So I resolved the issue by using Stuffit Expander instead of 7zip for Mac. I can only assume that 7zip for Mac which has worked for me in other situations was unable to properly unpack the VM download properly. I did not change anything to the file other than use Stuffit to unpack it which took about 5 minutes. When using 7zip the unpacking process took 5 seconds and the all the files were there but obviously not valid. With Stuffit it just worked.
I am facing errors while trying to run the VMX file. The error I get is 'VMX file is corrupted'. I have downloaded this thrice since yesterday and everytime get same error. I extracted using 7-zip and am using version 12 VMware player.
Can you please confirm the course and the file you are trying to download. The Marketing and Decisioning courses need VirtualBOX, and you will find a .vbox file not a .vmx file when you extract the zip file.
