Well, neither SIW or Belarc worked.
I did see licenses for the programs installed except for GameMaker.
However, throughout the process, I recalled that the key code was emailed to me (program was an online purchase). Even though I had the program for a few years, I still had the email in the archive folder (we can give gmail some bonus points for that).
Thanks for your help guys, and I will look to see what other programs out there may detect the keycode for future reference.
