Im currently experiencing a problem with the Oracle VM and CS50 2014 appliance. The VMware starts fine, but when I try to initialize the appliance, it comes up with the error - 'HostInterfaceNetworking-VirtualBox Host-Only Ethernet Adapter #3' (VERR_SUPDRV_COMPONENT_NOT_FOUND) I have adapter 3 de-activated on advice from other questions. it will not allow me to restore adapter 3 to on status, giving the error that it is an >invalid setting"<". Any suggestions here? I have tried everything I can think of or find, so far no love.
