"An error has occurred while trying to create a virtualbox host-only network interface" (Windows)

This error can be caused by multiple issues:

• If you are using Windows 10, this may be caused by Hyper-V which interferes with VirtualBox. Please make sure Hyper-V is disabled when using Genymotion Desktop. See Genymotion Desktop and Hyper-V (Windows 8/8.1/10) for instructions.

• If this doesn't apply to you, there may be an issue with VirtualBox Host-Only interfaces. To fix this, please follow these instructions:

  1. Open Windows Settings > Network & Internet > Change adapter options
  2. Right-click on VirtualBox Host-Only Ethernet Adapter
  3. Select Disable
  4. Right-click on the interface again and select Enable

• If the above doesn't work for you, please try the following:

1. Open Windows Settings > Network & Internet > Change adapter options
2. Right-click on VirtualBox Host-Only Ethernet Adapter
3. Click on Properties and then Configure
4. Click on the Driver tab
5. Click on Update Driver
6. Select Browse my computer for drivers. Now choose Let me pick from a list of available drivers on my computer.
