How to fix error error-invalid-function in Windows 11

Solution Steps

1. 1 First, identify the context. If the error appears when using a specific device (like a USB drive), try plugging it into a different port. Sometimes the port is faulty.
2. 2 If it's a program, try running it as administrator. Right-click the program icon and select 'Run as administrator'. This gives the program more permissions to access hardware.
3. 3 Update the device driver. Press Windows key + X and select 'Device Manager'. Find the problematic device (it might have a yellow exclamation mark). Right-click it and select 'Update driver'. Choose 'Search automatically for drivers'. Windows will search online for the latest driver.
4. 4 If that doesn't work, uninstall the device driver and restart. In Device Manager, right-click the device and select 'Uninstall device'. Check the box 'Delete the driver software for this device' if available, then restart your PC. Windows will reinstall the driver automatically.
5. 5 If the error is related to a file system, run a disk check. Open Command Prompt as administrator (Windows key + X → Terminal (Admin)). Type 'chkdsk C: /f' and press Enter. You'll be prompted to schedule a check on restart. Restart your PC and let it run. This scans for and fixes file system errors.
6. 6 If the error persists, it might be a compatibility issue. Try running the program in compatibility mode. Right-click the program, select 'Properties', go to the 'Compatibility' tab, and check 'Run this program in compatibility mode for' and select a previous Windows version.
