inno setup - Can I disable uninstall confirmation message?

Question

Basically the title says it all, can I skip Are you sure... message box part and run uninstall right away?

Answer 1

That message is not shown only if you run the uninstaller in silent or very silent mode. So only if you run uninstaller with /SILENT or /VERYSILENT command line parameters. If you're going to get rid of that message, you can create shortcuts with one of the mentioned parameters and optionally modify setup's registry key (e.g. My Program_is1) where you can append the parameter to the UninstallString key value. That will uninstall the application without this prompt even from control panel's applet.
