View Full Version : Run Script Before Installer Runs

02-15-2011, 11:03 AM
I'm running InstallShield Express. Can I run a script before Windows Installer checks for an installed version? I would like IS to simply replace a file when the user executes the setup. I have a script that runs the Uninstall and would like it to run first thing.


Please tell me what parameters to change so Windows Installer doesn't throw the already installed message. I've changed the Product Version, Product Code, Upgrade Code and I can't find the right combination. Changing the Product Code works but then there are multiple installs in the Control Panel-Add/Remove.

I'm a newbie so please excuse any misuse of the terminolgy and also be gentle... :)
