Click the "Check for Updates" button: Note: This button checks for updated versions of the graphics card and driver database that is used for performance tuning.3.
If there is an update available it will ask you if you want to replace it by clicking "Yes": 4.
NVIDIA recommends using the Windows Add and Remove programs utility for their drivers.
If your smart card reader is already listed, you can go to the next step of installing the Do D certificates. Try this first: Go to Device Manager (Instructions are above), scroll down to Smart Card readers, right click the CAC reader that shows up below Smart Card Readers. Hit OK, then select Extract (lower right corner of this window).
Once the installer has completed, you will need to reboot your computer in order for the update to complete.
