How do I uninstall a InstallScript app with InstallScript MSI

[neal007]

I acquired a company and they used InstallScript projects for their app. I rebuilt the installers using InstallScript MSI. When my installation is run, how can I uninstall the InstallScript version in the process so the user doesn't have two of the same application? It only has a Product code and not all the codes of MSI as you know.

Any tips would be appreciated. I don't know a lot about straight InstallScript projects.

Take a look at the UninstallApplication function in InstallScript. You should be able to run this at the beginning of your IS/MSI project to remove the old project.

Hope that helps,

Chris,

Works great. One more question. When I call the Uninstall, the old application shows the MODIFY, REPAIR, REMOVE dialog. I just want it removed. How can I configure the uninstall call to do that?

thanks!!

Keep in mind these are not MSI installs but instead they are straight InstallScript applications. I just prompted the user to click REMOVE when they see the app uninstall dialog, I think I'm set. Thanks for the help!

One other option for you Neal is to run the uninstall silently. You'd need to make an .iss file first (ie run the uninstall with the /r parameter) and then call it with a /s and a /f1 which would point to the setup.iss. But if you're happy with the Remove option just run with that.
