A driver is a software component that enables communication between your computer's operating system and a hardware device, such as a mouse. Without a driver, your computer won't be able to recognize or interact with the device. In the case of the IMICE GWX7 mouse, the driver is necessary to configure the mouse's settings, adjust its sensitivity, and ensure smooth cursor movement.
: Ensure the mouse is connected via the USB receiver before running the installer so the software can detect the hardware. imice gwx7 driver link
