Hello,

I am looking for a solution to protect an Excel document to be opened on one
computer only. On other computers, the Excel document should show a message
like "This document cannot be opened on this computer" or just fail to open.

The idea is to protect intellectual property in that document (and to
prohibit its usage, so a simple cell protection wouldn't be enough).

Third party solutions would be OK too.

Any answers would be highly appreciated!

Thank you,
Fabian
