Hi,
I create my first applications and wondering how advertising an uninstallation.
1. Do I need create a new app only for uninstallation only?
1a. If so only put the uninstall commandline on the installation program location
1b. How detecting a program was uninstall? During the installation a Windows installer product code will appear and then it is easy to target the presence of this product code. But there is not condition saying "if not exist".
