NOD 32bits vs 64bits

I have a laptop (Intel Core 2 Duo T6400 @2Ghz with 4GB of RAM).
Nowadays, my main OS is Vista Home Premium (x64).

My question is about which version of nod32 (v.3.0.684) is better for me: nod32 32bits or nod32 64bits.
I think it's no necessary 64 bits version, but if both of them are stable versions and there are no difference about memory usage, I think the x64 version will work fine.


Sorry for my poor english ;-)

Thank you.

 

Surely if you are running a x64 OS you'll want to install the x64 version!

Probably something to do with driver signings as well to enable installation on a x64 system.

 

my drivers works fine (my pc manufacturer's CD have support for x86 drivers and x64 drivers)

 

¿no issues with x64 version? ¿same speed x86 and x64?
help me choose one of them, guys! :-D

 

If you use a 64 bit OS you should use the 64 bit version. If you use a 32 bit OS you should use the 32 bit version.

 

Exactly!

 

thank you
