Can anyone guide me on how to setup my deployment project so that users can customize thier own settings in app.config? Which special folder in the File System browser should I add, Personal Data, Application Data, or Programs Menu? How do I add the app.config to the folder? What about the project output, should it also be in the same folder? If so, should the project output be taken out of the Application Folder, in other words, exist in one place? I tested my deployment and was shocked that the icon only opened on the test user's pc after installation. I have custom settings in the app.config file that have default values, but must be configurable for user specific settings. Please, any help is really appreciated. I've been searching the web to no avail for a solution. Thanks.
