    64bit guest O/S will not install

    wingtip Novice


      I've just installed ESXi 3.5 U2 on an HP Proliant ML370 G4 Server and trying to create a new 64bit Windows 2003 Guest Vitual Machine.  After creating the Virtual Machine and booting up on the Windows CD VMware says the following:



      "Attempting to load an x64 operating system, however this CPU is not compatible with x64 mode.  Please install a 32bit x86 operating system."



      The ML370 is a x64bit processor so I'm not sure what I'm doing wrong.
