Hi,

I have installed virtualbox 4.3.10-93012 on my laptop, windows 8.1 enterprise update 1 64-bit, cpu: i7-2820QM, intell hardware virtualization turned on.
Yet when creating a vm in virtualbox, I do not have the option to select any 64-bit versions ?

Best regards,

If another virtualization program is running and not "cooperating" you must disable it or uninstall it. You must make sure Hyper-V or XP-mode is not enabled on the host.
