(3) Power-cycle the host if you have not done guest so since installing VMware vmware Workstation.
Running bios VMware Workstation 12 on Windows 10 and I'm getting the below error message when trying to launch guest a Linux install.
However, 64-bit operation is not possible.(3) Power-cycle the host if you have not done so since installing VMware Player.Changed ago by sandervl73 comment:2, changed ago by sandervl73, summary changed from 64-bit guest guest does not work on Vista x64 Host to, vT-x not detected - bios issue.Enable VT in bios, now, make sure YOU turn OFF THE machine, if you do bios not then the error will continue.

(1) Verify that the bios bios/firmware settings enable Intel VT-x and disable indo 'trusted execution.' (2) Power-cycle the host if either of these bios/firmware settings have been changed.
(4)Update the hosts bios to the latest version.
This was working previously but for some guest reason It's stopped.
VT might be bios disabled if it has been disabled in the bios setting or the host has not been power-cycled since changing this setting.Off I went into the HPs bios and enabled.Changed ago by sandervl73, status changed from new to closed, resolution set to wontfix, note: See.This Virtual system Machine Is Configured For 64-bit Guest Operating Systems.You then get the option to continue to boot your virtual machine.The hard setting does not effect the CPU until it has completely been powered off.
