I have developed a large 90mb excel calculator application that i need to
protect. I have had a few people hack into in a matter of minutes, getting
past the passwords.

Does anyone have any suggestions or know how to really protect my code

Don't use excel. Create a compiled addin (xll???). It's beyond me.

Don't use VBA. Use a language (VB/C/C++/vb.net) that can be compiled.

You may have self-protection built-in to your program.
Not many people will want to install a 90mb file on their machine.
Reducing the file size should be your first objective.

An Excel add-in is nothing more than a hidden workbook.
You can see the list of add-ins available on your computer by going to
Tools (menu) | Add-ins.
To find out more about Com add-ins, see Chip Pearson's write up at...

It is not light reading.
