Error when adding

[Picard]

I have VirtualBox 6.0 and I tried to add a .vbox that I had been using earlier this year, but I got an error message regarding the Guest Additions. This has happened to some others that I've also used earlier this year and I have no idea of how to solve this. They were used on a previous release of VirtualBox before I recently updated to 6.0. Can anyone help me?

The message means just what it says. You already have that file registered. You cannot register it again.

Open the virtual media manager, click the Optical disks tab and remove the existing VBoxGuestAdditions.iso .
