VERR_SUP_VP_NOT_SIGNED_WITH_BUILD_CERT (-5667) error after 7 upgrade

[lphilpot]

I just upgraded from 6.1 to 7.0.6-155176 on Windows 11 and now when trying to launch a VM I get this error. How do I sign the VM?

You shouldn't have to, if I understand correctly.

1. Uninstall Virtualbox and reboot.
2. Go to "C:\Windows\System32\drivers", look for any files called 'Vbox*.sys' (there could be up to 5) and delete them.
3. Reboot again.
4. If you have any 3rd-party security or anti-malware software, disable the living daylights out of it for a moment.
5. Reinstall Virtualbox using right-click-Run-As-Administrator.

That did it, thanks.
