First you need to check that the problem is indeed a missing driver. Look in Device Manager. Under "Imaging Devices" you should see an error symbol. If there are no error symbols in Device Manager, it means the webcam itself is faulty so installing a driver for it is pointless.
If all it needs is a driver though, you can download it from the LG support website:
