[Interest] [interest][QT Installer Framework] how to overwrite or reinstall with existing app

[peterlingoal]

Thanks for the reply.

If uninstalling is the only solution, is there any way to invoke it at the
beginning of installation process? Sorry I am new to QT installer
framework, so please give me some guidance. Thanks.

regards,
