how to know wich X2 version im using: x32 or x64?? if dont remember which one I´ve chosen while installing, any way to know? cant find where... 
my pc is w7 x64

Click on "Help" and then on "About SONAR", which is at the bottom of the list of choices.  If you are using 64-bit, there will be a line that tells you which build you are using, and if it is 64-bit, it will end with "x64".

There's a discrepancy between what you say about your PC in your message, and the specs you show in your sig, by the way.
 
 

Well I guess you're talking about your Laptop as the specs suggest that's the only one X1 64bit could be installed on.

Firstly, the above option will tell you just fine but here's another possibility.

Right click the Sonar Icon: If the target path is C:Program Files\Cakewalk then it's 64. If it's C:\Program Files(x86) then it's 32.

Hope that helps

thanks to both.
wr what u mean? about 4gb ram in a x32 system? actually I have 6 gb only recognize 3,25 obviously... I´m  thinking of moving to x64 but things are working fine this way on x32 so i think I´ll keep the same until I really need to uograde

What I was talking about was that in the body of your message you said your PC was x64, but your sig says 32 bit.
