Problem Description:
I am a third-year student. I am on the computer network this semester. The teacher asked to install Huawei eNSP software. The installation process went smoothly until it was installed in the dependent component VirtualBox-5.2.44, and a problem occurred. Windows prompted that this application cannot be used on this device. As shown in the picture: 
I have no choice but to install the latest version of VirtualBox-6.1.38-153438-Win to match with eNSP. Online bloggers recommend using version 5.2.xx, the highest is not more than 5.2.44, but it is true The end of the road, bite the bullet and do it. After the installation is complete, I find that everything is normal (on the surface).
But when eNSP is opened, the system prompts an error message VirtualBox version is not supported, as shown in the figure: 
Then when adding and starting the router AR1, it finds that it cannot be started, and prompts error code 40, as shown in the figure:
Cause Analysis:
So I searched for a solution online, because I know that the version of VirtualBox I installed is wrong, so after I tried n methods on the Internet (vm virtual network card settings, software reinstallation...), this error still cannot be solved. I finally refocused my attention on the problem that VirtualBox-5.2.44 could not be installed. After browsing various forums and consulting information, I finally found a solution, and successfully installed VirtualBox-5.2.44 through this move, and it is perfectly compatible with eNSP software. The solution is as follows.
Solution:
**1. Open windows security center
2. Find Device Integrity
3. Click Go to Settings in Device Integrity
4. Click Kernel Isolation Details in Kernel Isolation
5. Select Off in the Switch option of Kernel Isolation
6. Finally restart the computer to install **
Conclusion:
Everyone must be cautious when installing software. If you encounter problems that cannot be solved, you must read more, learn more and try more. Do not download software from other bad websites or other websites that are not guaranteed, because I learned from the teacher that there are Because the students downloaded software from an unknown website and installed it, they kept making mistakes and couldn’t solve it. Based on the principle of safety first, they should try their best to choose websites and software with high security for downloading. So I downloaded it from the blogger's post on this site, thank you here, and attach a link for friends in need to download, respect the originality, start from me.
