How to delete application folder on uninstall

Question

1. I have created a setup using Setup project in VS 2010. It install my application into program files folder lets say XXX. My application further creates some files and folder into XXX folder. At the time of uninstall it delete every thing whatever create by setup while files and folder created by my application remains there in XXX.

2. I wrote some custom code to delete the folder (XXX) using installerclass but does not executes when user uninstall from control panel while executed successfully when uninstall from Setup created by me.

The first step would be to modify your application so it writes its data in per-user locations instead of the application folder. For example, you can use a custom folder in the current user AppData directory. This way you avoid permission-related problems.

For removing this folder, you can indeed use a custom action. If it's added under Uninstall in your setup project, it should run for both Control Panel and package uninstalls.

Try creating a verbose uninstall log and search for your custom action name to see what happens.
