Creating an Excel Add-in to Sell

Nov 29, 2013 at 8:03 PM
I am new to this discussion board and I would like to thank everyone in advance for taking the time to read this.

I have created an Excel VBA project that accomplishes a specific task. I would like to convert this to an add-in and possibly market and sell. From the online reading I have done it appears to make the project secure it would be best for me to create an add-in using visual studio. I am familiar with excel and vba but not visual studio or Excel-DNA. I would like to protect/lock my project, also I am looking for a means to authenticate users much like how you need a product key to use purchased software. This is where I am in over my head and I am looking for any advice or guidance. Basically, how would someone sell an Excel Add-in and prevent the user from distributing my add-in.

thank you.
