NVIDIA Driver is not installing for windows 7

Nvidia drivers will be installed by using these steps.
Right click on the setup file of the driver (exe file).
Go to Properties.
Click on 'Compatibility' tab.
Tick 'Run this Program in Compatibility mode'.
Select 'Windows XP Service Pack 2' there.
Hit Apply, And install the same file by double clicking it again..!!
I am sure it will do the trick.
