This shows that the ASP Pop 3 component is not installed on your server.
You must have got a dll file by name pop3svg.dll as part of your downloaded file.
You should put this on the server in \<windows installation directory>\system32 folder.
Then you should run regsvr32 pop3svg.dll from command prompt. This should bring a window saying successful registration. (If not, please check the path where you are now. Please change your working directory to \<windows installation directory>\system32)
Then it should work.
If the server is not in your control, you have to send this request and this file to server administrator.
