Web client doesn't download the plugin ZIP.

I have copied the vcplugin.zip on the web-client server at the following location: "C:/Users/Administrator/Desktop/vcplugin.zip"

After copying i run my plugin registration utility by providing it the following URL: "file:///C:/Users/Administrator/Desktop/vcplugin.zip"

The registration succeeds but the web-client gives the following error and the plugin cannot be seen:

<ERROR>

Thanks in advance.

Thanks,
