     How can i understand which version i need to download?

    Laptop versions:
    1.xx can only be updated using 1.xx versions
    2.xx can only be updated using 2.xx versions (normally 2.xx version are labeled "not for upgrades")
     
    Desktop versions:
    P01.xx can only be updated using P01.xx versions
    P11.xx can only be updated using P11.xx versions (normally P11.xx version are labeled "*not for upgrades")

    "L" BIOS versions are Linux OS dedicated (example P01.xxL)
     
    * what does it mean "not for upgrades"?
    During the windows 7 to 8 transition, some PC models had different BIOS versions from factory, related to the installed OS.
    Windows 8 PC got an UEFI BIOS
    Windows 7 PC got a "Legacy" BIOS

    So PC with Windows 7 installed from factory can't use the "not for upgrades" BIOS version, even if they were upgraded to Windows 8 or 10, since the factory BIOS was a different version compared to PC with Windows 8 from factory.

    ------------------------------

    Most of recent Acer laptop models support both Hyper-V and VT-x* (not AMD CPU models), they are both enabled even if those options are hidden on BIOS.
    If your laptop has an Intel CPU, you can check if you CPU/system supports virtualization instructions, using Intel Processor Identification Utility:
    If your laptop has an AMD CPU, AMD-V is disabled by default on BIOS and can't be enabled.

    Devices using Windows 10 Home will need to upgrade home to Windows 10 Professional or Enterprise to use Hyper-V. Windows 10 requirements can be found here:
    * If Hyper-V is ON, VT-x will not be available; Hyper-V must be OFF to have VT-x recognised by virtual machines.

    Turn OFF Hyper-V
    Open a Command prompt with administrative rights (Admin)
    type
    bcdedit /set hypervisorlaunchtype off
    exit
    Reboot your OS
    or
    Go to Control Panel -> Programs -> Programs and Features -> click Turn Windows features on or off -> un-check Hyper-V -> click OK
    Turn ON Hyper-V
    Open a Command prompt with administrative rights (Admin)
    type
    bcdedit /set hypervisorlaunchtype auto
    exit
    Reboot your OS
    or
    Go to Control Panel -> Programs -> Programs and Features -> click Turn Windows features on or off -> check Hyper-V -> click OK
