If this is not your first time running LDPlayer, the loading failure may be caused by the incompatibility between LDPlayer and the software on your computer including Graphics Driver, Virtual Technology, antivirus software and so on. In such situation, you can try the following methods to fix the problem.


Check Whether VT is Enabled on Your Computer

VT is a very essential part that can make better use of the resources of the CPU on your computer to boost the performance of emulator. If the VT is disabled on your system, you can open it to solve the loading failure issue. You can learn more details about VT from this article:How to enable VT (Virtualization Technology).


Update Your Graphics Driver

Besides the VT-related issue, the out-of-date graphics driver may also cause the loading failure issue with LDPlayer. Thus, you can check this article: How to update the graphics driver to know more details about graphics driver update.


Turn off the Antivirus Software and Reinstall LDPlayer

We ensure that LDPlayer is a very clean and safe emulator for mobile players. But sometimes, some antivirus software, like Kaspersky and McAfee, will clear some important components of LDPlayer due to wrong identification. Thus, if the issue can’t be fixed by the above methods, you can try to turn off the antivirus software first and reinstall LDPlayer.


The virtual box headless frontend has stopped working at 50%

Generally, if you find that the virtual box stops working at 50% while you are loading LDPlayer, the most likely reason is that the graphics driver on your computer has crashed or been damaged. There are also three ways for you to fix this issue.


Update or Reinstall the Graphics Driver

First of all, when the virtual box stops at 50%, you need to open the diagnostic information from the menu in the upper right corner of the emulator window. If the "OpenGL" option is on the 1.1.0 version or blank, it means the graphics driver on your system has crashed.  

Update Graphics Driver

So, you can try to update your graphics driver first when that happens. (More details about how to update graphics driver at this article: How to update the graphics driver.) And then, you can also try to reinstall the graphics driver on your computer if you still can’t load LDPlayer. You can search Google for information on how to reinstall the graphics driver for your computer.


Enable VT on Your Computer

You can also check whether the VT is enabled on your computer through diagnostic information. If the VT is disabled, try to open it. This article: How to enable VT (Virtualization Technology) may give you some help.

Turn Off Antivirus Software, Other Computer Games and Restart LDPlayer

When you are loading LDPlayer with some antivirus software and computer games running in background, the antivirus software and PC games may hinder the running process of LDPlayer. Hence, turning off those programs and restart LDPlayer may help you fix the problem.


Under Other Circumstances

In addition to the above situations, you may also face that the virtual box headless frontend has stopped working at 30%, 71%, 86% and so on. Never mind, all the above methods can be applied to those situations.


LDPlayer is stuck at 94% When Opening Multiple Instances

If it is the case that the subsequent opened LDPlayer is stuck at 94% when multiple LDPlayer are opened, you can try to close the LDPlayer that was stuck at 94% and create another new LDPlayer.

If the newly created one cannot be opened normally, you need to check whether it is overflow problem of temporary storage of CPU, memory, or graphics card.

If there is an overflow of occupancy, you need to check whether there is a problem with the parameter settings of the emulator. For details, please refer to: How to open as many instances of LDPlayer as possible.

If it still cannot be opened normally after setting the parameter, it may be a bottleneck in computer hardware equipment, or some hardware equipment has energy consumption limits. In this case, you need to replace hardware equipment or turn off its energy consumption limit to solve this problem.
