HAXM installation error

[Mohammad_A_1]

Hello

I'm trying to install HAXM but I get this message every time

This computer meets the requirements for HAXM, but Inter Virtualization Technology (VT-X) is not turned on.

HAXM can not be installed until VT-x is enabled.

I enabled it in my laptop BIOS but still get the same message

is there any thing to enable or do with BIOS or windows?

I have HP EliteBook 6930p

and running windows 7 ultimate 

thank you in advance.

Check BIOS -> Execute Disable Bit option. Also check on Windows -> System Properties -> Data Execution Prevention. It should work after you enable these options.
