Smart Client Deployment

I've created a little application that fires from a web link and does some functions. I cannot get the application to fire consistently on all machines in my office. I followed all the instructions for setting security and such on the machines, and I still cannot get the app to fire flawlessly on each machine.

On machines it will not fire, I'm getting an XML error as it tries to find the application's .config file. The webserver is set up properly because some machines are connecting and firing the exe with no trouble.

Where does app.exe.config file need to sit in order for all clients to get it?
TIA
