  • For the latest CS50 you complete the assignments on CS50 IDE which is a web-based "integrated development environment" that allows you to program "in the cloud," without installing any software locally, so you don't need VMware. Check the course at edX. More specifically the pset1 of week1.

You should try to install the VMware again and step by step as given in manual (the link is given by Christos ). And use the latest version of VMware.
