'VirtualBox Host-Only Ethernet Adapter Driver Error

I installed virtual box in my computer and it said device driver installation failed. i tried to manually update the Virtual Box host only ethernet adapter but windows gives an error message saying "Access Denied"

My computer is running on Windows 7 and my virtual box version is 4.2.12

And When I try add host-only network via Virtual Box it gives an error saying "Failed to create host only network interface"

Please Help.



Solution 1:[1]

  • Go to the lefttop corner of VirtualBox manager.
  • File-Preferences-Network-Host-only networks.
  • Remove these that you have, if any. (acknowledge as root)
  • Add a new one. (acknowledge as root)
  • Check its existence in cmd - ipconfig
  • Choose it using Host-only connection in Network of your virtual machine.

Maybe, you haven't administrator rights? Then you won't get acknowledgement window, and you really can't create it.
