**What exact error appears when trying 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 **VirtualBox is outdated** or its configuration has been modified.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. |
