I decided to do direct updates of the files vs updating the modules within the file and using the "Microsoft Visual Basic for Applications Extensibility 5.3" and therefore getting the "Trusted App" issue on Excel 03/07.

I could have detected the setting that would cause the issue, and either explain what needed to be performed to avoid the issue or pointed the user to a web site that explained what to do. This is a hassle that I just didn't want the user to go through....

Thanks for your help & suggestions.
