ASP Upload Component AspUploadv3.0 installation problem

Today, download the ASP upload set up--aspuploadv3.0, although the function is powerful but when the installation still encountered problems.

found that the first run of Server.CreateObject prompted no permission to invoke the component, although it has been assigned the permissions of the folder after file upload but still encountered the same problem.

After querying the data, it was possible that my IIS did not have permission to invoke my installation component. Locate the installed file directory, add IIS access permissions, run the page, haha problem solved! and learned a trick!
