I have installed VMware 11 for my windows pc but i am unable to find the link to install Cs50 appliance. please do suggest solution to this problem as where to find the link for the latter.
Visit the official link provided by the course and follow the steps. https://manual.cs50.net/appliance/2014/#how_to_install_appliance
I had the same problem. I kept returning to the Appliance installation instructions (the link posted by ChrisG) but found no reference to installing the CS50 Appliance Virtual Machine. The actual link for the Appliance VM is sort of hidden away within the instructions to install VMware (for Windows: https://manual.cs50.net/appliance/2014/workstation/).
As you'll find on that page, the link you want to download the CS50 Appliance is http://mirror.cs50.net/appliance50/2014/releases/29/appliance50-2014-vmware.ova
