When you create the vmware guest, you might have specified in the wizard &quot;Windows 2003&quot; (without 64bit).<br />
That's the only thing I can think of....<br />
Even with a 32-bit CPU, you can still install 64-bit guest OS if you specified so when you create the virtual machine. I've done x86_64 Redhat 5 guest OS, on my 32-bit laptop.<br />

Nope, I picked Windows Server 2003 Standard x64 Edition which is exactly what I'm trying to install. Thanks for the quick reply though, I appreciate it.

I'm attempting to install a VM of Windows Server 2003 Standard x64.<br />
<br />
However, when I try to do so I get the following message:<br />
<br />
&quot;Attempting to load an x64 operating system, however this CPU is not compatible with x64 mode. Please install a 32-bit x86 operating system.<br />
<br />
Setup cannot continue. Press any key to exit.&quot;<br />
<br />
<br />
<br />
The server has a 64-bit CPU and OS so I'm not really sure where to go from here. I've read that this can have to do with the way VT is setup in the BIOS but it doesn't really explain what I need to do.<br />
<br />
<br />
Can anybody provide any guidance? Thanks in advance.

Unable to install 64-bit Guest OS in VMWare Server

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
