A method of associating advertisements with a computer software product includes loading an executable software file containing software code that upon execution carries out a software program, parsing instructions in the loaded executable software file, presenting the parsed instructions in a user interface, receiving transformation instructions to be applied to the executable software file, and applying the transformation instructions to the executable software file to produce a transformed executable software file. The transformation instructions include location information for displaying an advertisement before, during, or after execution of the software program.
