VirtualBox not working after Windows update

Post by codeskyraider »

I had a Windows update applied today. When my laptop rebooted, VirtualBox no longer works. As soon as you try and run the program, I get an error message. "Windows cannot access the specified device, path or file."

I am a local administrator. I have version 7.0.6 installed. I can browse to the folder. I tried uninstalling and reinstalling the software. If I look at the permissions to the executable, it says I have full control. Nothing seems to fix it. Any ideas?

This may likely be something for Microsoft to help on. But first try another reinstall of Virtualbox, per this procedure:
  1. Uninstall Virtualbox and reboot.
  2. Go to "C:\Windows\System32\drivers", look for any files called 'Vbox*.sys' (there could be up to 5) and delete them.
  3. Reboot again.
  4. If you have any 3rd-party security or anti-malware software, disable the living daylights out of it for a moment.
  5. Reinstall Virtualbox using right-click-Run-As-Administrator.
