Usually, complete with a device or a computer, there are always disks on which the installation drivers are located. In this case, you just need to start the disk and follow the instructions.
If the automatic installation does not start, then you need to Open the disk through My Computer, find and run the setup.exe file there.
If there are no disks, then you need to look on the Internet
