Silverlight 5 In a trusted browser application

Question

I am working on a Silverlight5 application. We have to open one Exe from Client Pc. Since we are trying to use a trusted application "In the browser" and it works in the local host, but we are trying to use the IP address instead of Localhost, and then again the application cannot open Exe.

We are trying to sign the application with a test certificate and install in trusted root certificate authorities and a trusted publisher

Now it worked with Localhost, as well as with the IP address, but inside My Pc, but did not work in Network Pc.

Please imagine what things are missing or what should I do

Answer 1

I got my question, the problem with the testing certificate, when I use the actual certificate (from verisign) my application works as expected, it opens exe from the client machine.
