Method 1: Updateyour NVIDIA graphics driver

The “Access Denied” problem probably caused by an old, wrong or missing NVIDIA graphics driver. So you should verify that your graphics adapter has the correct driver, and update it if it doesn’t.

There are two ways you can update your NVIDIA graphics adapter:manually or automatically .

Option 1 – Download and install your driver manually

NVIDIA keeps updating drivers. To get them, you need to go to the NVIDIA website , find the drivers corresponding with your specific flavor of Windows version (for example, Windows 32 bit) and download the driver manually.

Once you’ve downloaded the correct driver for your system, double-click on the downloaded file and follow the on-screen instructions to install the driver.

Option 2 – Automatically update your NVIDIA graphics driver

If you don’t have the time, patience or computer skills to update your NVIDIA graphics driver manually, you can do it automatically with Driver Easy .

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version, it takes just 2 clicks (and you get full support and 30-day money back guarantee):

1. Download and install Driver Easy.

3. Click the Update button next to the audio driver to automatically download the correct version of that driver, then you can manually install it (you can do this with the FREE version).

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. (This requires the Pro version which comes with full support and a 30-day money back guarantee. You’ll be prompted to upgrade when you click Update All.)
