Nothing that cannot be circumvented. Also, how do you plan on "locking the
user out?"

Hi all,

I have developed a spreadsheet that I am planning on selling. I am
offering
a free trial of my spreadsheet, and after 30 days, it lock the user out.
This does not stop the user from downloading another version.

Is there anything in excel or some coding that will remember if someone
has
downloaded the trial version before?

Any help would be much appreciated.

Thanks

Jason
