VirtualBox on Windows 10 Fall Creators update

Hi Neil,

Compatibility issues could be one of the reasons why you're having this issue. We suggest that you try to roll back from Fall Creators update:

• Go to Settings > Update & security >
  Recovery.
• Click on Get started in Go back to the previous version of Windows 10
  section.
• Select the reason for going back to the previous build > Next.
• Click No, thanks if you're offered to download latest updates.
• Select Next to continue > Next > Go back to earlier build.

You may also contact the VirtualBox support to check for its compatibility with Windows 10 version 1709.

Feel free to post back should you need further assistance.

Hello,

The system finds VirtualBox and suggests to uninstall it manually, to run the update, but I am unable to find any app/program containing it. It's not shown in the Uninstall or Change the Program list. I do not have any Oracle installed on my PC either.

Kind regards,

TK
