This virtual machine is configured for 64-bit guest operating systems. However, 64-bit operation is not possible

I have windows 7 64x professional Laptop , then i download a new VM on it , but when i try to mount an ISO imag for windows server 2008 i got the following error :_

**This virtual machine is configured for 64-bit guest operating systems. However, 64-bit operation is not possible. This host supports Intel VT-x, but Intel VT-x is disabled. Intel VT-x might be disabled if it has been disabled in the BIOS/firmware settings or the host has not been power-cycled since changing this setting.

(1) Verify that the BIOS/firmware settings enable Intel VT-x and disable 'trusted execution.'

(2) Power-cycle the host if either of these BIOS/firmware settings have been changed.

(3) Power-cycle the host if you have not done so since installing VMware Workstation.

(4) Update the host's BIOS/firmware to the latest version.

For more detailed information, see http://vmware.com/info?id=152.**

So what is causing this error?

2So what is causing this error? - you've definitely checked the obvious idea that the error message means what it says and says what it means and that your BIOS settings need to be configured as described above? – Rob Moir – 2013-05-10T10:34:58.727

thanks for the reply, but this is my first VM instaltion , so i would like to know if these is any supporting documentations of how i can solve this issue? – None – 2013-05-10T10:37:29.210

There's a decent enough explanation on the vmware knowledge-base article that you've included above as to what's going on and what to do. Beyond that, none of us can tell you what precisely how to do it for your laptop because this is going to be something that's specific to the BIOS in your computer rather than some standard we can rattle off for you that will work everywhere. – Rob Moir – 2013-05-10T10:40:16.717

5Here's a shot in the dark - perhaps enable VT... – Jim B – 2013-05-10T14:17:46.300

Do what the man said: Enable VT-X in the Bios.
Sometimes it is also called Hyper-V. (For some obscure reason it often is hidden in the "security" section of the Bios.)

Most computers ship with the setting disabled by default. Some computers (especially laptops) are technically capable of VT-x but the Bios doesn't show it so you can't enable it.
In that case you are sheer out of luck.

thanks a lot for your reply, but i can not figure out how i can enable this on Intel core i7 on windows 7 64x on an HP laptop? – None – 2013-05-10T10:44:46.067

3By reading the manual, or searching the fine Google – mfinni – 2013-05-10T15:29:02.517

I get this error every time my Windows 7 Dell desktop restarts after a windows update. My CPU does support vitualization, and the BIOS is properly configured, but somehow the restart puts it in a weird mode.

Simple shut-down, and power on fixes the problem.

This is not an answer to the original question. Please ask your own question (referencing this one for context if it helps). Lack of reputation does not stop you asking a question.

A windows update did trigger the problem for me too, but shutting-down/powering-on did not fix the problem on an HP pro laptop. I had to re-enable virtualization in the BIOS, as it had been somehow disabled. – Khopa – 2015-02-24T08:41:38.733

Go to BIOS by pressing ESC on powering on. Go to System Configuration -> Device Configuration or similar Check the enable VT-x Save Power cycle Should work

You should check the intel website to see if your processor supports VT-X/ Hyper-V

If Intel says it has VT-X... try upgrading the BIOS/enable it.
