To get Analytic Solver to work in Excel, you need to register the plugin before launching Excel. This can be done by going to

Start –> Frontline Systems –> Analytic Solver Platform –> ASP Application Manager

This will produce a box that will allow you to register or unregister the Analytic Solver plugin. Once you have registered the plugin, open Excel and you will see the Analytic Solver ribbons across the top.
