Can not run WIndows8 64-bit guest on WIndows 8.1 64-bit host

[Florida9797]

I'm running VMware WorkStation 10.0 on a Windows8.1 64-bit computer. I tried creating a new VM (Windows 8.0 64-bit). When I try to open the VM I get a dialog stating that Binary translation is incompatible with long mode. When I click on the OK button, I get a dialog stating this VM is configured for 64-bit quest operating system. However, 64-bit operation is not possible.

Soon after upgrading from Windows 8.0 to 8.1 my BIOS were upgraded.

I tried VMware WorkStation 10.1, same bad results.

What do I do now?

Run SecurAble to first determine if you have enabled the necessary CPU features in the BIOS and let me know the results.

While running windows 8.0 I was able to create and run VMs. Soon after upgrading from Windows 8.0 to 8.1, my BIOS were upgraded.

While eating dinner I realized the solution which I'm now doing. After the BIOS were updated I forgot to "Enable Virtualization Technology".
