On Windows 10, one day VirtualBox will not boot any VMs. Upon checking logs, I got this error:

Fatal error: supR3HardenedDllNotificationCallback: supR3HardenedScreenImage failed on 'C:\Windows\system32\SHELL32.dll'

I searched this error on google and found other people with similar issues, such as this: https://forums.virtualbox.org/viewtopic.php?f=6&t=66364

However, I want to fix the root cause of this issue instead of using an old version of VirtualBox without the OS verification checks.

I chose to repair the DLL file on my system, using the instructions on this site: https://support.microsoft.com/en-ca/help/929833/use-the-system-file-checker-tool-to-repair-missing-or-corrupted-system

Basically, run the Command Prompt as Administrator, then run the following commands:

DISM.exe /Online /Cleanup-image /Restorehealth

Then

sfc /scannow

The DLL files should now be repaired and VirtualBox should work as expected.

  • I had the same issue, except with 'C:\Windows\System32\clbcatq.dll'. This worked. Thanks! – Benjamin Berman May 18 '20 at 17:09
