View Full Version : Upgrade an existing install

12-19-2001, 07:47 PM
I have a previous Installshield project working fine. Right now I have a new version of my Software an need to modify the project so if you run it and there is a previous install, it will run an upgrade process.

The problem is that everytime I run the install again in displays the dialog box that prompts to repair/modify/remove the existing install.

I know how to get rid of this on a new project, but I can't find a way to do it in an existing project.

Any ideas?

Thanks so much. :)

The OnMaintUIBefore event is what you have to change

See (for creating updates/maintenance packs):
