Restoring Functionality to AMD GPU Software on PCs

Users who need to fix AMD Radeon Software not working can’t open that app and access its settings. Are you among those users? If so, you can fix AMD Radeon Software not opening on a Windows PC with the resolutions below.

1. Run AMD Radeon Software as an Administrator

Users typically select to run AMD Radeon Software without admin rights from the context menu. Instead, try running AMD Radeon Software as an administrator to see if that helps. You can do that by pressing the Windows logo button + S, inputting AMD in the search box, and selecting Run as administrator for the AMD app found.

If that works, permanently set AMD Radeon Software to run with elevated privileges. To do so, follow the steps in this article about always running apps as an administrator . However, note that you can’t permanently set the AMD Radeon Software MS Store app to run as administrator.

2. End the RadeonSoftware Process Tree

First, check if Task Manager shows a process for AMD Radeon Software. If it does, that effectively means the app is already running in the background. Terminating the process tree for AMD Radeon Software might then fix the issue. You can close the RadeonSoftware process tree like this:

Press the Ctrl + Shift + Esc keyboard key combination to activate Task Manager.
Select Task Manager’s Details tab.
Look for and right-click RadeonSoftware.exe to select the End process tree option.
Click on the End process tree button to confirm.

3. Delete the CN Folder

Corrupted profile data often causes the AMD Radeon Software to stop working. You can fix that by deleting the CN folder, which contains Radeon profile data. Erasing that folder rebuilds the profile. This is how you can delete the CN folder:

Utilize the Windows key + R keyboard shortcut to access the Run dialog.
Type %appdata% into Run and click OK to access a Roaming directory.
Click AppData in Explorer’s folder location bar.
Open the Local subfolder inside the AppData folder.
Click the AMD folder to go inside it.
Right-click the CN folder and select Delete.

Alternatively, you can try erasing a specific file within the CN folder, which users have also confirmed works. To do that, open the CN folder to view its contents. Right-click the gmdb.blb file in that directory and select Delete.

4. Disable and Re-enable the AMD Radeon Graphics Adapter

Disabling and re-enabling the AMD graphics adapter is another potential resolution users confirm can kick-start AMD Radeon Software. You can disable and re-enable the AMD graphics adapter on your PC as follows:

Double-click the Display adapters category to extend it.
Right-click the AMD Radeon graphics card to select Disable device.
Click on Yes when asked to confirm the selected option.
Wait a minute and right-click the AMD Radeon graphics card again to select Enable device.

6. Restore the Previous AMD Driver Installed on Your PC

Sometimes buggy new graphics drivers can cause issues, which is why NVIDIA and AMD release hotfixes. If your PC already has the latest AMD driver, restoring the previous one installed could be a viable solution for some users.

You can do that by selecting a Roll Back Driver option, as covered in our guide on rolling back graphics drivers on Windows .

7. Set Windows 11/10 to Clean Boot

A conflicting background program could be another factor for AMD Radeon not opening. The best way to remedy this possible cause is to configure your PC to clean boot and restart it. This will disable third-party apps and services automatically starting with Windows.

To apply a clean boot, you’ll need to remove apps and services from the startup with Task Manager and MSConfig. Our article about performing a clean boot on Windows includes specific instructions for how you can disable the required startup items. Restart your PC after disabling the startup items and select to open AMD Radeon.

8. Edit the CN Registry Key

Editing the CN registry key is resolution confirmed to fix the “Radeon Settings and Driver versions do not match” error message some users see when they try to start AMD Radeon. This registry fix involves entering a new value for the DriverVersion string in the CN key. These are the steps for applying this registry fix:

First, open the Display adapters category within Device Manager, as instructed for steps one and two of this guide’s fourth resolution.
Click the AMD graphics card with the right mouse button and select Properties.
Select Driver on the tab bar.
Drag the cursor over the driver number on that tab and press Ctrl + C to copy.
Close the properties window and Device Manager tool.

Now, open the Registry Editor on Windows before continuing.

Clear the registry address bar to input the following key location there:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\AMD\CN
Double-click the DriverVersion string in the CN registry key.
Clear the Value data box.
Press the Ctrl + V hotkey to paste the copied driver version number into the Value data box.
Select OK in the Edit String window.
