Virtualbox virtual machine terminates at startup with exit code 1 [closed]

Question

The following error comes when I start a Machine.

The VBoxStartup.log contains this entries.

f0c.10d8: supR3HardenedWinVerifyCacheProcessWvtTodos: 0 (was 0) fWinVerifyTrust=1 for '\Device\HarddiskVolume2\Windows\System32\winmmbase.dll'
f0c.10d8: Fatal error:
f0c.10d8: supR3HardenedMainGetTrustedMain: LoadLibrary "C:\Program Files\Oracle\VirtualBox/VirtualBox.dll" failed, rc=1790
79c.fac: supR3HardNtChildWaitFor[2]: Quitting: ExitCode=0x1 (rcNtWait=0x0, rcNt1=0x0, rcNt2=0x103, rcNt3=0x103, 2239 ms, the end);
534.1200: supR3HardNtChildWaitFor[1]: Quitting: ExitCode=0x1 (rcNtWait=0x0, rcNt1=0x0, rcNt2=0x103, rcNt3=0x103, 2653 ms, the end);

This occurred after windows update. I'm running version 4.3.30 r101610 which I updated recently. The problem exists in previous two releases also (tested).

Answer 1

Go to explorer, right-click C:\Program Files\Oracle\VirtualBox\drivers\vboxdrv\VBoxDrv.inf and select Install

This will reinstall the VirtualBox kernel driver. After that VMs should once again start as expected.
