NVIDIA Control Panel Access denied – Won’t apply settings

The NVIDIA Control Panel is a central control panel for devices that run the NVIDIA Graphics Drivers. It comes bundled with the driver package itself and hence does not need to be downloaded or updated separately. Some users have been reporting that when they are making changes to the configuration inside the NVIDIA Control Panel, it throws out the Access denied error. The whole error reads,

Access denied.

Failed to apply selected settings to your system.

In this article, we will learn how to fix it.

NVIDIA Control Panel Access denied

Some of the practical methods to effectively fix the Access denied error for NVIDIA Control Panel is as follows:

1. Run the nvcplui.exe file as an Administrator.
2. Restore the most recent version of its folder.
3. Update or Rollback drivers.

1] Run the nvcplui.exe file as an Administrator

Open File Explorer and navigate to the following path:

C:\Program Files\NVIDIA Corportation\ Control Panel Client

Locate a file called nvcplui.exe, right-click on it and select Run as administrator.

3] Update or Rollback drivers

First, you need to uninstall the current version of installed NVIDIA Graphics drivers from your computer. Next, download and install the latest version of the driver from NVIDIA’s official download page.

We did this method instead of directly updating the driver because we have to reset all the configuration of the driver stored on that computer.

Alternatively, you can try to roll back the current version of the driver and check if that fixes your issue.
