Either VirtualBox is not installed, not installed correctly, or there's a version mismatch between the extension pack and the main software. I lean toward the latter explanation.

Well it's definitely installed. It has been working, so it must've been installed correctly.

If it's a version mismatch, how do I go about solving it?

As mpack already said, the extension pack must match the version of VirtualBox you are running. You appear to be trying to load the extension pack for version 6.1.8. What version of VirtualBox are you running? If you are not sure, check by clicking Help then About VirtualBox.

When you download Virtualbox there is a link for the matching Extension Pack. If you go to the Older Builds pages, each Virtualbox version has its matching EP version.

With the default install location on Windows hosts: "C:\Program Files\Oracle\Virtualbox", Virtualbox must be run as Administrator to install or uninstall the EP. The EP goes in "C:\Program Files\Oracle\Virtualbox\ExtensionPacks", and Admin privileges are required to copy into "C:\Program Files".

If all else fails the Extension Pack download file is really just a gzip archive (according to 7-zip) and can be installed manually:

Note that if your Virtualbox is installed in a special-permissions folder, like C:\Program Files, you will still need an admin password.

Reboot your host PC to ensure that no Virtualbox processes are running.
Open the archive with a gzip-compatible archive program.
Extract the folder named '.' (a period) to an empty folder in your Home folder.
Directly inside the extracted folder should be the Extension Pack files.
Rename the extracted folder to "Oracle_VM_VirtualBox_Extension_Pack" (without the double quotes).
Move the extracted folder inside {wherever-Virtualbox-is-installed}/Virtualbox/ExtensionPacks
Start Virtualbox. The Extension Pack should be recognized in File menu, Preferences, Extensions.
