VS 2005 Deployment project - how to launch uninstall of product first?

[Rob R. Ainscough]

I have an older application that was installed via msi approach (setup via
InstallShield), however, it has a different product code than the new
version (setup via Deployment Project in a VS 2005 solution) I want to
install. As a result my newer version does not identify the older version
because the product code is different (so it doesn't uninstall it first).
What I'd like to do is setup a Launch Condition that first uninstalls my
prior version (I know the product code) before installing my newer version.

Can someone point me in the correct direction?

Thanks, Rob.

Look up msiexec.exe /x or msiexec.exe /uninstall.
You can pass it a product code.

HTH,
