I know there were threads about this before, but my question is very specific.

There is a product that does almost what I am looking for called DoneEX: it takes an excel spreadsheet, converts it into .exe format, puts hardware locks on it and optional trial periods/expiration dates. BUT, it converts all the formulas in the original excel file into binary code to hide them, and this technology is faulty. The formulas don't work half the time and it also slows down the application significantly.

Does anyone know of a similar application that doesn't convert formulas to binary code? Thanks,

Daniil.
