I’m having trouble after installation; can you help troubleshoot?

**How to troubleshoot post‑installation issues with Genymotion**

> *If you’re still seeing errors after installing, try the following checks first. If the problem persists, let us know the exact error message and your OS version.*

| Step | What to check | Why it matters | Quick fix |

|------|---------------|----------------|-----------|

| **1️⃣ Verify system requirements** | • Windows 10/11 64‑bit, macOS 12+ (Intel or Apple Silicon), Linux (Ubuntu 22.04 + or similar)
• Hyper‑V (Windows) or VirtualBox (Windows, macOS, Linux) enabled
• At least 4 GB RAM (8 GB recommended) | Genymotion needs a modern hypervisor and enough memory. | Enable Hyper‑V: *Settings → Turn Windows features on or off → Hyper‑V*
Or install/enable VirtualBox. |

| **2️⃣ Check the license/login** | • Logged in with your Genymotion account
• License key (if you’re on Desktop) is still valid | A failed login or expired license will stop the UI from launching. | Re‑login → Settings → “Login” → “Logout” → “Login” again. |

| **3️⃣ Run the “Check installation health” test** | • In the Genymotion menu, click **Help → Check installation health** | Detects missing components, firewall/VPN interference, or network issues. | Follow any on‑screen suggestions (e.g., allow firewall, disable VPN). |

| **4️⃣ Resolve common startup errors** | • **“Booting…” stuck** – increase RAM, disable Quick‑Boot, or reset the VM.
• **“Unable to start virtual device”** – ensure VirtualBox host‑only network is present.
• **“Your CPU is incompatible with virtualization technologies”** – enable VT‑X/AMD‑V in BIOS. | These are the most frequent stumbling blocks. | For Quick‑Boot: Settings → Virtual Devices → “Use Quick Boot” → uncheck.
For host‑only network: open VirtualBox → File → Host Network Manager → create a network. |

| **5️⃣ Update to the latest Desktop version** | • Genymotion Desktop 3.9.0 (released 24 Apr 2025) includes many fixes for Android 15, QEMU, and Apple Silicon. | Older builds may lack recent bug‑fixes. | Go to Settings → “Check for updates” → install. |

| **6️⃣ Inspect logs** | • Log files are in `~/.Genymobile/genymotion/` (Linux/macOS) or `%APPDATA%\Genymobile\Genymotion\` (Windows). | They often contain specific error codes (e.g., “VM not found”, “No matching host key type”). | Copy the relevant section and paste it into the **Support → Contact us** widget. |

| **7️⃣ Disable conflicting software** | • VPN, corporate firewalls, or other virtualization software (Docker, VMware). | They can block network traffic or virtualization features. | Temporarily turn off VPN or add Genymotion to firewall exceptions. |

| **8️⃣ Reinstall if needed** | • Uninstall → Delete leftover folders (`C:\Program Files\Genymobile\Genymotion` or equivalent).
• Re‑download the installer for your OS from the official page. | A clean reinstall can resolve corrupted files. | Use the official installer: . |

| **9️⃣ Use the online troubleshooting page** | • From the Genymotion menu → **Help → Troubleshoot** | Runs connectivity & device tests in‑app. | Follow the prompts to test network, ADB, screen streaming, etc. |

### Quick FAQ for common error messages

| Error | Likely cause | Quick solution |

|-------|--------------|----------------|

| **“Network error – can’t connect”** | Firewall blocking Genymotion or ADB | Add `genymotion` and `adb.exe` to firewall exceptions. |

| **“Invalid reply from server”** | Time‑outs due to slow internet or proxy | Check proxy settings; try a wired connection. |

| **“Your CPU is incompatible with virtualization technologies”** | VT‑X/AMD‑V disabled in BIOS | Reboot, enter BIOS, enable virtualization. |

| **“Android 15 is slow (Windows)”** | Hardware not fully supported yet | Try running the device in a *cold* boot (restart the VM) or use a lower‑level Android version. |

| **“Device screen is black or frozen”** | Quick‑Boot or GPU issue | Disable Quick‑Boot, increase RAM, or switch from VirtualBox to QEMU if you’re on Linux. |
