This is better suited to the Workstation forum (error is from workstation attempting to boot the VM).
The features you talked about are actually about passing 64-bit cpu and VT to the VM.
The error message is about enabling 64-bit VM Virtualization in your physical systems BIOS.
So reboot your computer, go into your BIOS or UEFI (newer systems) and see if there is an option for Virtualization, VT-x, or something of that nature.
