    v1 v2  
    1414#5 Additional research performed (related to VB not supporting 64 bit), and I found that it is related to Virtualization support on BIOS ('Virtualization technology' opcion). BTW that option was not enable on my BIOS (so I activated that option on my BIOS BUT nothing happend, I mean issue with 64 bit support persist after this change). I read this option comes not activated by default and that this is not mandatory for 64 bit support. As after enabling that option 64 bit support was still absent, I think that option is not mandatory to have 64 support working. So, why 64 bit is no longer supported on my VB if I made no changes on HW nor any configuration (like BIOS level) and considering that this was working prety well prior I reinstalled VB?
    1515#6 I am using a laptop proBook 6460b
     16#7 I read the issue can be resolved using 'VirtualBox-4.2.18-88781-Win', after it was installed I could see 64 bit system support was available again, however I could load my VM 64bit I previously created ('Win7x64_Template') and an error message pops-up ('VT-x/AMD-V hardware acceleration has been enabled, but is not operational. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot.
     17Please ensure that you have enabled VT-x/AMD-V properly in the BIOS of your host computer.)
