Setup project - Silent Uninstall.

[Lamrin]

Here's the context. We have a setup program that will deploy an application
to our clients. The exe deletes all of its files when the user exists from
the application (I know this is odd, it's a requirement of the project). To
run the application again, the user must run the msi twice. The first time
to remove the previously installed application. The second time to install
the application again.

In the setup project I've set the RemovePreviousVersions property to True.
In this context, the msi will actually do a silent unstall before the
reinstall as long as the version number of the setup project has been
incremented. How can I replicate this same behavior (silent uninstall then
reinstall) without incrementing the version number of the setup project?

Seems like CustomActions might be a possible solution. Has anyone had any
similar experiences?

Thank you!

I've tried to understand what you are describing...

It sounds to me, like a "Repair" from the installer should be run before the
second execution of the application. I would think this happens
automaitically if the files are marked "critical" in the setup program.
