Access Device Manager, simpliest way is to search it via task bar "search option"
Locate your device. In many cases it appears under "Other devices" section or elsewhere with incorrect name. Disconnect/reconnect phone to see where it pops up in device manager
Right click on line that belongs to your device and select "Update driver software..."
Choose option to manually direct to driver location
Locate downloaded driver folder, mark it and click "OK"
Now that path to driver was applied, click "Next"
Message afterwards indicates installation result
Appearance of device should change in Device manager too
Repeat this process for all lines that belong to your device
