How to solve the FastCGI Error in installing a dongle on the server

The error message is shown in figure

FastCGI ErrorThe FastCGI Handler was unable to process the request.
Error Details:

Error Number: 5 (0x80070005 ).
Error Description:

HTTP Error 500-Server Error.
Internet Information Services (IIS)

Cause: The iisexecutable program disabled by the website security dog. The fastcgi.exe program is executed. FastCGI is equivalent to a third-party program being executed by IIS (the same behavior as that of an abnormal program, so it is intercepted)

Solution:When the website security dog interface is started, the FastCGI path is obtained by default and automatically added to the built-in white list. If the user finds that there is still an interception problem, you can manually add the FastCGI path to the "application path whitelist" list on the "disable IIS program execution" interface, as shown in the following figure.
