I have developed an add-in recently, i want to share it as a free license to everyone, but i want to strongly protect the VBA codes inside its modules.   i know that the password protection is the weakest,  also sharing the workbook and making it then add-in also is breakable, the shared workbook "project is Unviewable" works but i have found that users still break this.

i was wondering if there is any commercial software or any encryption software that can buy license that can protect my excel add-in.

You can try LockXLS I cannot vouch for the software as I have never tried it, but it was highly recommended on this site before.

If you have VB6, you should be able to copy your code into that and save it as a COM add-in.  That would be a lot more secure, IMO.

But a VB6 COM add-in would not work on 64 bit Office...
