I'm working on softwares that were built without taking into account that they could be sold in modules. At the present time, when we (the company I'm working in) sell the software we have to install all features on the client. I know that currently there's a technique using "Prism" that solves this situation, but our softwares are already made and we can't start them all over again.

Does anyone know any technique on how to handle this situation?

My thanks in advanced
