I have a Dell E6400 - running Windows 7. I am using VMware Workstation 6.5 - trying to create a Debian VM. Upon trying to install the 64-bit version of it, it said:

this host is vt-capable but vt is not enabled

I've now enabled virtualization in my BIOS, restarted (cold restart - even pulled the battery out!) But it still says it's not enabled.

I've updated to the latest BIOS, tried again - BIOS said it's enabled, VMware says it's not!

What can I do?

There is a small utility that will tell you if you are ready for 64-bit VMware called SecurAble. With both texts saying YES, you should be set for 64-bit.

If it still won't work, then try and post the exact computer model and motherboard type, someone might lead you on the right track.

You need to switch off the execution disable bit too. I can't tell where on your BIOS that option is. Most likely under some security tab or submenu.
