[Solved] Win 11 VirtualBox Failed to open a session ...

Post by cadayton »

I don't see the "VirtualBox NDISx Bridged Networking Driver" on any of my adapters. Where do I find the driver?

It is installed as part of the Bridged Networking option when installing Virtualbox.

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