Cause analysis
This problem is estimated to be caused by the fact that the Activex control does not contain a digital signature. Therefore, we only need to disable the security level of IE from loading the unsigned ActiveX control. The specific steps are as follows:
1. Run IE as an administrator
Find the IE browser icon on the desktop, right-click it, and click "run as administrator" in the pop-up menu. Then, open the ActiveX control we installed.
2. If the above method is invalid, press "Alt + T", and then click "tool-Internet option" to open the following (you need to open IE browser first ).
In the pop-up internet window, click "security", select "enable protection mode", and click "custom button" to enter the custom security settings window.
In "ActiveX control and plug-in", configure "download unsigned ActiveX control" as "prompt", as shown in the following figure.
Click "OK"-"yes" to continue.
Press "OK"-"OK" twice to close.
Finally, restart the browser to install the ActiveX control.
We can disable this plug-in after it is used up to ensure security.
