I have a photography business and I wrote two applications that I thought would benefit me. I have used both of them for about a year now and believe I have worked out many of the bugs.

I would like to offer these applications for sale as shareware and was looking for some tips on preparing my final package. For example, how important is it to put the application in the Program Files folder? Currently, I am having difficulty installing into this protected folder. Are there any encryption algorithms I should avoid in creating an un-lock key?

Any help would be greatly appreciated.
