Make sure you have Intel Virtualization turned on in the bios. Without this you will not be able to run 64 bit guests and That is in the BIOS of the host machine.

I found the information from this article here:

I bet if I took a short and informal poll and said the majority of virtualization users were excited to hear VMware’s announcement of 64-bit guest operating system support, most of you would agree with that statement. And following up on that statement, I would also bet that only a small minority of those same individuals would know exactly which processors offered compatibility and met the hardware requirements. Personally, I didn’t even think about it. I just assumed I could purchase a 64-bit processor and then be on my way enjoying a fun filled afternoon with my virtual machine running a 64-bit guest operating system. After all, what’s the problem?

After doing a little bit of reading and research, I was directed to a VMware knowledge base solution appropriately titled “Hardware Requirements for 64-Bit Guest Operating Systems”. Exactly what I needed.

The question was simple. I want to use either VMware Workstation or VMware Server to run virtual machines with 64-bit guest operating systems. What are the hardware requirements for the host machine?

The answer was not so simple. As I feared, you simply cannot purchase any old 64-bit processor. But knowledge is power, and so I pass this KB article on to you, in the hopes that the answer can shed some light on the subject for those of you in the market to purchase new hardware in order to run these 64-bit guest operating systems inside your virtual machines.

VMware’s virtual machine monitor has traditionally used segmentation to provide isolation between the guest operating system and the virtual machine monitor. This is necessary because the guest operating system and virtual machine monitor share the linear address space.

AMD
Segmentation support is missing from the initial AMD64 processors (that is, revision C and earlier) while running in long mode. As a result, AMD64 processors prior to revision D do not have an efficient mechanism for isolating the virtual machine monitor from 64-bit guest operating systems.

A limited form of segmentation was reintroduced in long mode, in revision D AMD64 processors. As a result, AMD64 processors must be revision D or later to run 64-bit guest operating systems.

Note: Because AMD Opteron and Turion processors do not ship in revision D, AMD Opteron and Turion 64 processors must be revision E or later to run 64-bit guest operating systems.

Intel
Intel EM64T CPUs do not have segmentation support in long mode. If the Intel EM64T CPU is VT-capable, it comes with hardware virtualization support (Intel’s Vanderpool Technology). This hardware virtualization support allows Workstation and VMware Server to work around the lack of segmentation, making it possible to run 64-bit guest operating systems on Intel EM64T VT-capable CPUs.

32-Bit CPUs
Please note that Workstation and VMware Server require a 64-bit CPU to run a 64-bit guest operating system. While it is theoretically possible to emulate a 64-bit instruction set on 32-bit hardware, doing so most likely results in unacceptable performance degradation.

VMware distributes a free utility that can be used to determine whether or not your CPU is suitable for running 64-bit guest operating systems. You can download this utility from the VMware Web site at www.vmware.com/download/ws/#utilities. VMware Server includes this utility in its product distribution, so you don’t need to download an additional tool.

Workstation 5.5 and VMware Server 1.0 support virtual machines with 64-bit guest operating systems only on host machines that have one of the supported 64-bit processors:

* AMD Athlon 64, revision D or later

* AMD Opteron, revision E or later

* AMD Turion 64, revision E or later

* AMD Sempron, 64-bit-capable revision D or later (experimental support)

* Intel EM64T VT-capable processors (experimental support)

Note: In shopping for a processor that is compatible with Workstation 5.5 or VMware Server 1.0 64-bit guests, you may be unable to determine the revision numbers of a given vendor’s offering of AMD Athlon 64, Opteron, Turion 64, or Sempron processors. At this time, the only reliable way to determine whether or not any of these processors is a revision supported by VMware software is by noting the manufacturing technology (CMOS). Any of the AMD Athlon 64, Opteron, Turion 64, or Sempron processors whose manufacturing technology is 90nm SOI (.09 micron SOI) is compatible with Workstation 5.5 or VMware Server 1.0 64-bit guests. Using this information, you should be able to determine with the help of your vendor, or from the AMD Web site ( http://www.amd.com ) whether a particular Athlon 64 or Opteron processor model is compatible with Workstation 5.5 or VMware Server 1.0 64-bit guests.
