Did you run comregister.cmd as admin? Otherwise it's not able to change 
the relevant registry entries - and I faintly remember that it's best 
not to use comregister.cmd when a "proper" VirtualBox package is 
installed currently (forgot if it just causes trouble with uninstall or 
if there was some more serious trouble).

I'm not aware of generic COM logging (because that's what apparently 
fails)... you might try if manually starting VBoxSVC works around the 
error, because if it does it's definitely a registry problem and nothing
