Q1. No royalty, MS get their income as the recipient would also have to have
Excel.

Q2. Ridiculously insecure. Do not rely on it, it can be cracked in seconds.

Hello - I have a couple of questions about developing an excel
application.
Is there a royalty consideration or any other legal consideration
regarding
microsoft when marketing an excel app? How secure is a protected vba
project? I have never tried to crack one so I don't know.

Thanks,
