What Causes the Access Denied error in NVIDIA Control Panel?
There aren’t plenty of issues which may cause this error to occur on your computer. The problem is almost exclusively driver-related and there are several things you can do in order to try to resolve it. Check out the list below:
Solution 1: Clean Install of NVIDIA’s Driver
This is quite a straightforward way of resolving the problem and it’s definitely something you should try immediately. Reinstalling the driver won’t do you any harm and it’s recommended that you always have the latest drivers installed. Follow the steps below in order to perform a clean install of the latest NVIDIA driver.
Alternative: Rollback the Driver
For those who feel uncomfortable looking for the drivers as it can be confusing for casual users since you need to input information about your computer can use an alternative. It involves rolling back the graphics card driver. This process will look for backup files of the driver which was installed before the most recent update and that driver will be installed instead.
Solution 2: Run the Control Panel with Administrator Permissions
Another way of resolving this problem is simply by running the NVIDIA Control Panel client as an administrator. This should prevent the Access Denied problem as the access may be revoked if the program is run without admin permissions. Try it out below.
Solution 3: Replace the Previous Driver (for users who use System Protection/System Restore)
If you are using System Protection or System Restore on your Windows PC, chances are that the last known working driver files for the NVIDIA graphics card may still be around and you can access them easily. This may not work for everyone if the files aren’t backed up but it can be a good alternative rolling back the driver.
