your cpu doesn't support long mode use a 32 bit distribution

Hello guys,

I think it is a well known issue and i post it here because you may can give me a quick solution to this error.
Actually the message shouldn't appear to my case as i' m using a latest i7 4770 processor which supports as i saw VT, my board is a z87 and i think is also capable of doing many things, finally the VB has installed on Win 7 64 environment.
So my problem starts when i' m loading this ISO image to my VM and during the installation prompts me that message.
This ISO definitely works on ESXi as it has been tested there. any idea ....

1) 64-bit guests need hardware-virtualzation enabled in the hosts bios.
2) when creating the 64-bit guest you must select 64-bit in General -> Basic -> version.
3) If running Windows as host you must make sure hyper-v or xp mode is not enabled on the host. MS does not play well and wants it all.
