Hi Tracy
If a file is missing why doesn't it blow on startup instead of shutdown?
I hate to do this but here is a copy of the script used for building the Setup.exe. Maybe you can spot something.
Script follows this line:
; Script generated by the Inno Setup Script Wizard.
; SEE THE DOCUMENTATION FOR DETAILS ON CREATING INNO SETUP SCRIPT FILES!
