VirtualBox unable to start error: rc=-5640


If you see this error when trying to run a guest machine in VirtualBox:

(rc=-5640)
Please try reinstalling VirtualBox.
where: supR3HardenedWinReSpawn what: 1
VERR_SUP_VP_THREAD_NOT_ALONE (-5640) - Process Verification Failure: The process has more than one thread.


You may try this simple trick first. It takes about 1 minute of your time and may surprisingly work.

  1. Go to the Settings of the guest VM.
  2. Select System.
  3. Select the Motherboard tab.
  4. Increase Base Memory (in my case, I only increase it by 100MB).
  5. Start the VM.
