How to ask for removing user data while uninstall application?

Question

I use InstallShield Limited version 2013 to configure setup of my Visual Basic application. I save application user data.

Usually Uninstallation does not remove files of application.

While Uninstallation, I want to delete files with an alert of "Do you want to delete profile folder?".

Can anybody please suggest me way to achieve this?

Answer 1

Uninstaller doesn't delete things which has been modified/added by user. Because such added files doesn't present in File table of uninstaller.

To remove such files, create CustomAction. In CustomAction you can show MessageBox & accordinly you can delete a specific folder or files using Delete function.

Add this CustomAction in your execution sequence & set condition of "REMOVE=ALL", So it will execute only at uninstallation.
