I'm interested to know how to create Uninstall.exe, this wrapper would call OnUninstall Function code to execute a set of installscript driven actions (InstallScript MSI Project). I'm looking for an Uninstall.exe mainly for this reasons: - Cannot use Setup.exe -Uninst or -x because the CD/Source Media is always not present during uninstall. - You can always remove the program from Add/Remove program, but in my case my Application would be uninstalled by another InstallShield Application.
So, you are looking for a way to start the uninstallation of your program without using the original setup.exe? When you start the uninstallation via [Add/Remove programs], windows simply executes a command which doesn't depend on your setup.exe either. Check the HKLM/Software/Microsoft/Windows/CurrentVersion/Uninstall/{Your GUID}/UninstallString.
