Licensing an .exe

[LovinItAll]

I have written a script that I am selling. At this time, I hard code a user name in the precompiled script and the user is sent through an authentication process. I didn't think there would be a lot of demand for the script, so making changes, recompiling, and redistributing wasn't a concern.

Well, I was wrong. I am selling a bunch of these things, and everytime I make a change, I am forced to recompile each user's individual script. Has anyone here written anything that that uses registry values to "marry" their .exe to a unique machine? For that matter, is anyone aware of anything that has already been written to prevent an .exe from being distributed freely?

I know I can write code that authenticates against a database or an encrypted file, but I was hoping this issue may have already been addressed. I searched the forums, but I have not found anything as yet.

Thanks in advance....
