What exact error appears when you try to install Genymotion?

In most cases, the error message we see when starting the installation of Genymotion Desktop is:

> “Unable to start the virtual device”

This error usually appears when:

1. Virtualization is not enabled (VT-X/AMD-V). 2. VirtualBox is outdated or its configuration has been modified. 3. The user does not have administrator permissions in Windows. 4. The firewall or a VPN blocks the creation of the host-only interface.

What to do if you see that error

| Step | Action | Why it helps | |------|--------|---------------| | 1 | Restart your PC and verify that virtualization is enabled in the BIOS/UEFI. | The error usually disappears if virtualization is enabled. | | 2 | Update VirtualBox to the latest compatible version (for example, 7.1 or 7.2). | New versions correct incompatibilities with Genymotion. | | 3 | Run Genymotion as an administrator (right-click → “Run as administrator”). | It needs privileges to create the VM and the host-only network. | | 4 | Check the host-only network configuration: open VirtualBox → File > Host Network Manager and remove additional adapters, leaving only one. | Sometimes duplicate adapters cause the error. | | 5 | Temporarily disable the firewall/antivirus or add Genymotion to the list of exceptions. | The firewall may block the creation of the host-only interface. | | 6 | Check if a VPN is active and, if so, disconnect it. | VPNs sometimes interrupt the necessary network communication. |
