VirtualBox will fail to acquire the VirtualBox COM object, the application will now terminate

That may be due to an incorrect/incomplete VirtualBox installation actually...

1. Uninstall VirtualBox. Your VMs are going to be untouched. Reboot.
2. Download (if you haven't already) the latest VirtualBox and its matching ExtPack. Store them in a common location, i.e. not on "Desktop", or "Documents", but to "Public/Downloads" for example.
3. Uninstall (don't simply disable) all 3rd party antivirus. If you're afraid about your computer being vulnerable, pull the Ethernet plug, disconnect your WiFi, don't go browsing around.
4. Locate the downloaded file in Windows Explorer. Right-click on the installer and select "Run-as-Administrator", even if you are the administrator. At the end of the installation, choose to "Start Oracle VM VirtualBox". Do not worry if your VMs do not show up.
5. If you're going to install the ExtPack, go to File » Preferences » Extensions. Click on the icon with the orange, down-pointing arrow on the right. Select the ExtPack from the previous steps.
6. Quit VirtualBox. Re-start VirtualBox as you would normally, i.e. from the Desktop shortcut or the Start menu.
7. Update the Guest Additions (GAs) in your guest(s), if the GAs are available for a specific guest.
