I signed up for the Business Architect Essential (v6.3) course and I have been unable to download/run the PVS. I've tried on both a Windows 7 (64bit) and a Mac OS X (v 10.9.5) based machine and I cannot get it to work on either. On my mac, I followed the directions and was able to get an exe file to download but when I attempt to run it it says 'You can't open the application bae_63sp1_pvs_072613.exe because Microsoft Windows applications are not supported on OS X. On my Windows based laptop, I right click on the file and click Save target as and I get a message stating that the file name is not valid. I even tried putting the file that downloaded on my Mac into drop box and opening it from my Windows based laptop and I get the message 'The version of this file is not compatible with the version of Windows you're running. Any suggestions?
