Yes, upgrade your CPU or downgrade the version of VMware Workstation.

Hi,

To add a bit of background info to what the others already have said.


Starting with VMware Workstation 14 additional CPU requirements are needed.

A feature called "VMX Unrestricted Guest", see also: https://planetvm.net/blog/?p=3253

At the time when Workstation 14 came out the installer would not test for that and it confused a lot of people.

Especially as you cannot check for this feature on the Intel technical specification page about their CPUs.

The current Workstation installer however gives you a timely error, the one you saw. So at least you don't end up burning a lot of time.

While "upgrade your CPU" sounds nice, normally you can't upgrade the CPU of your machine to one that will work, without replacing the machine, as intel does not keep their CPU sockets compatible between CPU revisions. So it is more a "upgrade your computer" kind of thing.

An alternative approach is to install either an older VMware Workstation product (Workstation 12 or older) or another virtualisation product that does not have these requirements.
