Michael: I have a registration program that assigns a unique key to a

the software for that customer only. I did a trial version once where
I put a number of days check in my registration program. The date and
the number of days left was stored in two different places on the
system. One in a data folder and one in an appdata folder. If they
changed the system date than I knew it and shut them out. If they
tried to install on a different computer, they would have to activate
it. If they tried to find and delete the file with the date & number
of days in it, I knew that too. Simple yet very effective.
Hi Jeff,
Good ideas. For this app, it's really just a "get it into their hands
yesterday" kind of thing and it is definitely not a long-term solution
for them. I've already told them that I'd move them to the new app when
it's ready, but they want to get started now, so I'll give them the app
that's been working since 2003 with a timebomb of sorts in it. Quick
and dirty for the task at hand. Elegance not necessary for this
go-round. :-)
