How to fix error error-dynlink-from-invalid-ring in Windows 11

Solution Steps

1. 1 Press Windows key + R, type 'sysdm.cpl', and press Enter. Go to the 'Advanced' tab, click 'Settings' under Performance, then go to the 'Data Execution Prevention' tab. Select 'Turn on DEP for essential Windows programs and services only' and click Apply. This relaxes DEP restrictions that might be blocking DLL loading.
2. 2 Press Windows key + X and select 'Device Manager'. Look for any devices with a yellow exclamation mark. Right-click and choose 'Update driver'. If that doesn't help, right-click and select 'Uninstall device', then restart your PC. Windows will reinstall the driver automatically. This ensures drivers are compatible with the current security model.
3. 3 Open Command Prompt as administrator (Win+R, type 'cmd', press Ctrl+Shift+Enter). Type 'sfc /scannow' and press Enter. This repairs corrupted system files that might be causing the DLL loading issue. Wait for it to complete and restart.
4. 4 If the error occurs with a specific program, check if it has a 64-bit version. If not, try running it in compatibility mode: right-click the executable, go to Properties > Compatibility, and check 'Run this program in compatibility mode for Windows 7'. Apply and try again.
5. 5 Press Windows key + R, type 'regedit', and press Enter. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager. Look for a value called 'ProtectionMode'. If it exists, double-click it and set its value to 0. If it doesn't exist, right-click, select New > DWORD (32-bit) Value, name it 'ProtectionMode', and set it to 0. Restart your PC. This disables a security feature that might be too strict.
