>Have a program that uses Defox 9 for encryption and then inno setup to put the installation together.
>For some users the install works correctly and for others the Defox installation key must be entered every time they run the program.

One solution that's guaranteed to work: Stop using Defox.

Your work should be a gift unto others. People should be able to grow atop your knowledge and experience. It is not for us to erect invisible monopolistic fortresses around our work, hoarding our software so that unless others pay us money they are shut out! What kind of world is that where everybody builds walls around themselves? It is a world divided greatly, and nothing else.

Money does not edify, but rather only subjugates. Money does not unify, but only divides. It is instead people working together which always edifies, and it that which we should be striving for in this world always, and in all things.

We are all here together upon this Earth. People. Living people. It is for us to be working together, one to another, and not to be divided, but to be as one, pulling for each other with all that we are, with all we were endowed, gifted, and given (as by innate abilities, as well as opportunities).

In short, we are here to help each other, to grow together as a single people -- taking our right place as part God's creation.
