Bump! This solution just worked for me upgrading to 4.3.10 x64.

Many thanks John.

Thanks for the solution, worked first time without problems.

I had that issue too when upgrading from 4.3.8 to 4.3.10. The solution given here works (driver install), but is not really a viable solution for me since the VirtualBox installation is done in a script ran automatically (silent mode) on more than 20 build machines. The script exists so that I don't have to connect on each machine to install VirtualBox manually. If I have to go on each on them to manually fix the upgrade process, it kind of defeats the purpose of the script...

If the issue has benn present for more than four years, why is the installer not fixed yet?

The very first post fixed my issue, thanks.

I just upgraded to Version 4.3.12 and started getting the "Cannot access the kernel driver" error.

I did the install of the 2 inf files above which got rid of one error but the kernel driver persisted.

I am running Windows 7 and this is what fixed mine.

1. Exit VirtualBox
2. Find your VirtualBox application in your start menu.
3. Right-click select Run as Administrator.

Everything works now.

I tried this fix, installing those two things. When I do & reboot, my network connection is unable to work. I have to uninstall VBox to get my internet working now... Every time up do an upgrade VBox stops working EVERY TIME... I tried an older version & the network error still happens now... How do I un-do installing these two things?

Thank you

I had the same issue using windows 7

I opened cmd as adminitrator and ran "sc.exe query vboxdrv" and it said that is was not running so I just ran "sc.exe start vboxdrv" and everything got fixed

Go to
C:\Program Files\Oracle\VirtualBox\drivers\USB\filter
Select VBoxUSBMon.inf and click the right mouse button. Then pick Install.
Go to
C:\Program Files\Oracle\VirtualBox\drivers\vboxdrv
Select VBoxDrv.inf and click the right mouse button. Then pick install.
VirtualBox should now work again as expected.

From 8 years ago, this post still saving lifes. It worked great for me.
