first im sorry for posting it in here... if this is the right section...

drivers from their site supports win7 64 bits but when i install nothing happens... just an exclamation on the drivers...

Hello z3r0tech,

What does the Device status section in the General tab of the item with the exclamation mark in the Device Manager say?

You can try to install the driver manually by downloading the Windows 7 x64 driver (as you have already done) and extract/install it as explained in the Manual section of the Drivers page in the manual.

If that doesn't work, maybe installing the Desktop Experience feature helps.

Good luck!
