I am trying to Install Nvidia Software so that I may switch in between Nvidia and Intel HD graphics.
I have Following :
Lenovo T420s
Nvidia Nvs 4200m
Intel Hd . Intel Core i7
Windows 7
Problem is that my device manager shows that i have Nvidia 4200m installed on my device meaning thereby its drivers are installed. However whenever I run the installation software windows generates error and stops in the midst of installation.
