Recently came across this error (VirtualBox Kernel driver error) and here's the fix:
To find out more information on what is causing the error with Oracle VirtualBox run the following on a Windows command prompt:
sc query vboxdrv
this reported back the kernel driver has stopped:
Service_name: vboxdrv
type 1 kernal_driver
state 1 stopped
win32_exit_code 0 0x2
service_exit_code 0 0x0
checkpoint 0x0
wait_hint 0x0
It seems two device drivers are not installed by the installation program during a virtualbox upgrade, to manually this missing components type the following command:
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
