Not sure if its a bug or what suffice to say that I don't understand it either. For example, what happens if you replace setup.exe with another "app" like for example notepad.exe - everything seems to work ok ...

Can you or anyone provide me with a simple setup.exe example - something simple I can install that can be installed over-and-over again so we can test and re-test and get to the bottom of this ?
