Shut down everything VirtualBox and then run :-

Code: Select all

VBoxManage extpack cleanup

Check that this leaves the <VBoxExeFolder>/ExtensionPacks folder empty.

Then install the extension pack using the File|Preferences|Extensions panel.

Please post a VM log file. With the VM fully shut down, right click it in GUI. Select "Show Log" and save "VBox.log" (ONLY) to a zip file. Attach the zip here.

And what is the context in which you see that error message?
