HELP ME TO SOLVE THIS ISSUE!? Thank you

I was tried to set up a Virtual Machine with ESXi.

and download this file VMware-VMvisor-Installer-6.5.0.update01-5969303.x86_64.iso from VMWare

And when I click to start. The system displayed an error and I don’t know how to solve this situation

“This host does not support virtualizing real mode. The Intel “VMX Unrestricted Guest” feature is necessary to run this virtual machine on an Intel processor”

And my PC configuration is

HP Z400 Workstation 103C_53335X (HP 0B4Ch) – Desktop type

Intel(R) Xeon(R) CPU W3520 @ 2.67GHz (4C 2.8GHz/2.93GHz, 2.13GHz IMC, 4x 256kB L2, 8MB L3)
