Okay, I have an inherited InstallScript project that I am working with. The project uses "program ... endprogram" (so, if you don't know what I'm talking about, chances are you can't help me). I know this is not ideal. I'd love to change it, but updating 4000+ lines of InstallScript by myself when I maintain a good two dozen or so other installers isn't exactly time practical.
Anyway, for years now it has come along fine. Recently, I've had to make some changes that require little applets we wrote internally to be run during install. Obviously, this initiates changes that the installation project isn't aware of. One of the changes also requires that I run an applet on uninstall to undo some things we're doing during install. So here's my issue. There's no "uninstall" routine now. As near as I can figure, "uninstalling" from Add/Remove Programs simply removes the files and registry entries that the install project put there; it's automatic, or so it seems. I see no place in the code that appears to be any form of intentional uninstall routine.
So I have nowhere to add a LaunchAppAndWait to kick off this app. Given the nature of the project, if I add an OnUninstall event handler, will it even execute? If not, is there some way that I can guarantee that this gets executed?
