X64 systems in VirtualBox (5.1.10) are not available, images with x32 work

Win 8.1 main system, Hyper-V is not installed

INTEL Core i5 3570 processor , virtualization supported

In the list of VM settings, there are only x32 systems, x64 systems are missing.

Any idea what you can do? I tried to install version VB 5.0.30 - the same.

    Go to the BIOS - you need to set up explicit support for virtualization. After that, everything should work. https://stackoverflow.com/questions/20019231/vt-not-supported-when-installing-haxm

    I had a similar problem, I decided to enable the VT-d option in the BIOS
