When I first attempted to install a 64-bit Server on VMware, it gave me an error that the software was unable to recognize the hardware as 64-bit capable. Before installing the virtual machine, make sure that virtualization is turned on (in bios) on your system. For enabling virtualization on this machine the steps are as follows: restart system, press Esc, select F10 and enable virtualization by enabling VT options in BIOS/firmware and disable 'trusted execution'.Without configuring this option, VMware will not recognize your hardware as 64-bit capable. To get started, open VMware, click on the New Virtual machine option, select Custom (Advanced) and click Next.
