I placed a good copy of the dll file in the same dir that the password protect software exe lived. As before, the password software loaded, accepted the password (which I had previously placed on Excel) and failed to load Excel with the same dll missing error. I was just testing this software at the house for my wife who would use it at another location. I'm ditching my effort here (seriously not worth this effort) and will see if the software works on her XP machine later.
Thanks,
Mark
