So I recently updated VirtualBox to the newest version (5.1.28). Everything was okay, then I installed a Windows update. This might have conflicted with my drivers or something.
The error message:
Could not find Host Interface Networking driver! Please reinstall. Resultaatcode:E_FAIL (0x80004005) Component:HostNetworkInterfaceWrap Interface:IHostNetworkInterface {455f8c45-44a0-a470-ba20-27890b96dba9}
What I already tried: - Run as administrator - Reinstalled VirtualBox, chose the 'repair' option - Reinstalled Card Reader driver
Appreciate your time.
