How to add an activation code prompted

[ababenchrist]

I want to add an activation code prompted before install of a software application. I was wondering if you might have any subjections how I might achieve this. I know how to set up an autorun and a program installer wizard.

You'll most likely have to purchase something. see Product Activation, Network License Server Platform For The Internet Era: Orion, Safe Activation Service 1 - Protect and Manage Software Licenses from a Secure Vendor Account, & Trusted Activation by Nalpeiron for some examples.
