good day to all of you guyz !!!!

i had bought an a4tech office mouse with a 7 button on it. functions with the bundled software of the mouse.
the problem goes here because i am using the mouse for online gaming and the gameguard of the game i am playing is blocking the software of the mouse thats why the other button of the mouse is not functioning.
nid help pls... if i could just make the other button of the mouse to function like one of the keys of the keyboard without the software like configuring or altering some program of my pc like my 4th button of the mouse = numpad 1. pls help me on this guyz ....

tnx in advance....
