Removing prerequisites during uninstallation of main package

[nchounlapane]

On my main installer, I've added pre-requisites using the /NewPrerequisite command. Is there a way to uninstall the pre-requisites when the main installer is being uninstalled? It seems that using a powershell script wouldn't work since running it blocks any uninstalls if there is already one running?

Hello Nick,

In order to uninstall the prerequisite when the main package is uninstalled, you should use the "Allow uninstall" option.

If the prerequisite is an MSI package, the uninstlal command line will be completed automatically.

Otherwise, you would have to do so yourself (e.g. adding an uninstall command line).

Hope this helps!

Best regards,

This is actually what I needed. Since I added the prerequisite using /NewPrerequisite command, is there any way to update the prerequisite's Uninstall Command Line and enable Allow Uninstall from advanced installer command line?

Hello Nick,

I'm afraid that we do not have automation support for that specific request.

However, i will add this on our TODO list of improvements and it should be added in a future version of Advanced Installer.

Until that, you can check the checkbox manually and input the uninstall command line.
