The mouse does have a driver even if it uses the MS generic one. The "software to tune it" is itself the driver.
If the mouse came with the PC then take it back to where you bought it and let them sort it out.
Is the mouse a "special" or just a standard one. If so try a normal mouse and see what happens. If it works fine then the problem is almost certainly with the "Special" mouse software. Try installing it in compatibility mode.
