Is it possible to cancel a silent install on Windows

We have an installer wizard (written in .NET) which configures and kicks off a series of standard Windows installers. The installers are run silently. Right now, clicking "Cancel" on the wizard's dialog stops further installers from running, but does not stop whatever installer is running silentl开发者_StackOverflowy in the background.

Is there a way to send a installer running silently the equivalent of pressing the Cancel button on a non-silent install? (I could kill the installer process, but I expect that that will leave a half-installed (and probably non-uninstallable) mess behind.)

I'm not sure if you're creating new instances of these installers within your own installation wizard so I don't know how applicable this solution is going to be, but if you do have access to the actual (derived) System.Installer objects that correspond to the installers, calling the overridden System.Installer.Rollback() method of those objects should achieve the desired result. Let me know if this doesn't work and I can try helping you further.
