Bringing machine 'default' up with 'virtualbox' provider...

There was an error while executing `VBoxManage`, a CLI used by Vagrant

for controlling VirtualBox. The command and stderr is shown below.

Command: ["list", "hostonlyifs"]

Stderr: VBoxManage.exe: error: Failed to create the VirtualBox object!

VBoxManage.exe: error: Failed to instantiate CLSID_VirtualBox w/ IVirtualBox, but CLSID_VirtualBox w/ IUnknown works.

VBoxManage.exe: error: PSDispatch looks fine. Weird

VBoxManage.exe: error: Details: code E_INVALIDARG (0x80070057), component VirtualBoxClientWrap, interface IVirtualBoxClient
