GeForce 820M Driver installation problem

I have Dell Vostro 15 3000 Series laptop in which a 2 GB NVIDIA GEFORCE 820M GPU is attached. Driver software which is available in dell website can be installed and works properly but it is not updated. When I download updated driver from nvidia official website for my gpu, it’s not installing, only showing

“This graphics driver could not find compatible grphics hardware”

. But I am sure that I am choosing and downloading driver by providing correct GPU information on official website.

Please solve my problem.
