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

If this error occurs, try following these steps:

1. Reboot your PC

2. User account

Genymotion Desktop relies on VirtualBox 6.1 since v3.2.0. This version requires admin rights to install the necessary Host-only interface at first run. Make sure that your Windows user account has admin rights to run Genymotion Desktop properly.

3. Hyper-V

If you are using Windows 10 Pro or Enterprise, this error may be caused by Hyper-V which interferes with VirtualBox. Please refer to Genymotion Desktop and Hyper-V (Windows 8/8.1/10) for more details.

4. VPN

If you are using a VPN, please see Genymotion Desktop and VPN
