Hi: I have a Winforms project. I have xml and txt files for both read and write in the project. I have two ideas... Click Once (Publish tab on Menu Bar) and rolling my own installer MyInstaller.exe) and using a zip file for users to download and install. I would use Click Once but Googling I find a host of user permissions problems, trusted, elevated and all that jazz. First, has anyone used Click Once and if so can you help me out figuring out how to set permissions so a user can download and install my app without any nasty messages? Second, if I roll my own installer would I have the same problem of data files or content files requiring the user to mess with file permissions? Thanks: Rick USA
