4. Graphics rendering mode (switch the option between OpenGL+and DirectX ), and then check if you can run the emulator now.

5. Andriod version(check if your version is the latest and which version you’re using ). For instance, 511 means Andriod 5.

Second, make sure the type of your problem according to the system info.

2. Check the Virtualization technology is enabled or not.

If all the steps below can’t solve your problems, please go to the official website or store to see if a BIOS update is available. Please remember to follow the official correct steps to update, otherwise, you may encounter problems when starting your computer.

VT, also called Virtualization technology, is a technology that provides the ability to run multiple, isolated operating systems on a single piece of server hardware allowing a much higher level of resource utilization.

Why do you need to enable VT?

Virtualization technology could improve the performance of your computer and allow NoxPlayer to run more smoothly and faster.

How to check if you have enabled VT?

First Method:

Check the red question mark-“ ！” in the upper left corner of the emulator directly, If you see this mark, it means that you didn’t enable VT.

Second Method:

Check your system information, the emulator will automatically check if your computer enables VT.

Third Method

Use a tool called: LeoMoon CPU-V. It does not only detect if your CPU supports Hardware Virtualization, but also Detect if Hardware Virtualization is Enabled in BIOS.

If your check result shows a green check under VT-x Supported, it means your computer supports virtualization. If it’s a red cross, then your computer does not support VT, but you could still install Nox as long as you meet the installation requirements.

If your check result shows a green check under VT-x Enabled, then it means VT is already enabled in your BIOS. If it’s a red cross, then follow the following steps to enable it.

How to enable VT?

1. Check your system information int the emulator and Find out your BIOS type

2. Enter the BIOS interface: Press the shortcut Delete/ F12 continuously while booting the computer.

Special computer model reference:

Laptop: Lenovo THINKPAD  press F1, others press F2
Desktop: DELL press ESC, others press F12

3. Enable VT

• Find the corresponding VT option on the BIOS page. (Mostly called Virtual or Virtualization, in some cases VT-X or SVM)
• Click <Advanced>-> <Processor> (CPU)-> Virtual or Virtualization, for some computers, VT are included in Configuration or Security.
• Set the VT option to Enabled.
• Press Save (usually F10) to save and exit (Save & Exit).

Note 1: If you are running Windows 8 or Windows 10, there might be conflicts between VT and Microsoft Hyper-V technology. Please turn Hyper-V off following these steps: go to Control Panel->Programs and Features->Turn Windows features on or off->un-tick the box before Hyper-V.

Note 2: If your VT is enabled in BIOS, but the LeMoon check result still shows a red cross under VT-x Enabled, it’s highly possible that your anti-virus software has blocked this function. Taking Avast! for example, to fix this problem:

1) Open Avast anti-virus >> Settings >> Troubleshooting

2) Uncheck the Enable hardware-assisted virtualization, then reboot your computer
