The Virtualbox File Preferences General VRDP Authentication Library does not appear to be being found properly.
Whenever attempting to create a new VM, at Finish, I get an error message telling me that it cannot replace Virtualbox.xml with Virtualbox.xml-tmp. Permissions on both files are full access. If I try to hit finish again it gives a different error with chinese characters that I cannot read. It appears to have created the machine directory in .Virtualbox/Machines, but has not created the .vdi in .Virtualbox/Harddrives.
I appear to be able to get around this behavior by creating a new hard disk image before creating the new machine. I still get the error but if I exit out of virtualbox entirely I can then rename Virtualbox.xml-tmp to Virtualbox.xml manually. When I start up virtualbox again the machine has now appeared in the list.
I can run the new machine but must manually add the new hard disk image and an iso to do first boot from, the auto first run seems disabled.
