Hi,
I'm trying to create a VS2005 Setup Project. I have a config file
(MyApp.exe.config) that I need to deploy only the first time the app is
installed in a particular location. That is the file should not be
overwritten if a new version of the app is installed in the same location.
I know how to deploy the file but how do I prevent overwrite? Is it
something to do with the Condition property? I got completely lost in docs.
Any examples?

Thanks
