Default Protect Excel Worksheet to be opened on one PC only

Excel internal security is very weak and passwords can be easily cracked. No
matter how hard you try; any user with the intend of opening the files can
easily google and get a password cracker. So suggest not to use excel to
store such data...

If this post helps click Yes

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
