I am trying to run it on vmware player and I am getting this:
I am running Windows 7 64 bit as a host with no problem.
Please help.
Thanks
Did you try to follow the instructions in the message? Seems quite clear to me...

So, that is needed for VM to run 64 bit? Because as I said I am running 64 bit OS as my host without any problems. Also I was able to install W8 64 on VM but now it's not running?
Intel VT-x is required for 64-bit guests, because it provides facilities for protecting the host OS from the guest OS. Since you don't need this protection when you are just running a 64-bit host OS, you can run a 64-bit host OS without enabling VT-x, as you have observed.
If you were able to install a 64-bit guest OS on this system in the past, then it is likely that Intel VT-x was enabled at that time. Some firmware fails to re-enable VT-x after resuming from a deep sleep state. If you are able to run 64-bit guests after booting your system, but not after it has hibernated, then you may need a BIOS update.
Please try to follow the recommendations in the message dialog. Let us know how it goes.
