Selling work books

[Iceman007]

Hello all, I have made an E-Book using excel. It has a around 45 workbooks.
Each work book has around 9 pages in the book. I think I have 5 basic formulas in each page which are all the same formulas through out.

I would like to sell this one day as a digital download or on CD from an
e-commerce website.

Is there a way where I can set it up ,if someone wanted to purchase the book from me, that I could some how tie in a licensee key or activation key ,that the book would only be able to be used and read on one computer?
Making it where they could not share with anyone.

You can protect your worksheets or even whole workbook using build in password protection, but this won't limit usage of your e-book to one computer.
You can do something like when you registered your Windows or Office -you first getting a key and then you have to registered your copy with Microsoft and getting activation code so when you trying to install this same copy on different computer the key is already registered with MS and won’t allow to run this same copy )but this would require a small database and presumably good programing skills..<o></o>
