Duo Security Authentication Proxy "Error Code : 2 , Error Message : The system cannot find the file specified."

While installing Duo Security Authentication Proxy using attendant installation the application is not installing and failed with Error Code : 2 , Error Message : The system cannot find the file specified.

How could we solve this case?

Hi @Grace_S !

This error message is commonly seen when the user’s permissions are not sufficient to install a Windows application. Does said user have administrative rights to perform software installations on the target server? Performing “Run as administrator” may also prove successful.

Hope this helps!
