VMware Workstation 17 Player can run 64-bit guest operating systems. However, your host machine's CPU must support hardware virtualization (Intel VT-x or AMD-V) and be enabled in the system BIOS or firmware.

The key difference between Workstation Player and Workstation Pro:

1. Snapshots: Only available in VMware Workstation Pro, not Player.
2. Cloning: Pro supports both linked and complete clones, but Player does not.
3. Distance Connectivity: Pro can connect to distant servers, which is lacking from Player.
4. Licensing: Player is free for personal use, while Pro requires a purchased license.
5. VM Management: Pro offers facilities for managing many virtual machines at the same time, whilst Player only supports single virtual machines.

VMware Workstation 17 Player is a desktop hypervisor for personal use that enables users to run different operating systems simultaneously on a single Windows or Linux computer. It provides an isolated environment for testing, development, and running several operating systems.
