Script to change Action Sequence records in an MSI

Question

To solve a problem listed here I\'ve got to change the InstallExecuteSequence .RemoveExistingProducts record in an MSI.

I want to do this as part of the build proces

Answer 1

The solution provided by Ryan addresses part of the issue I am facing. It does perform full uninstall, followed by install.

However, I have another issue, in my case some of the programs are running in the background. Before the installer can run, the installer complains that some of the files are in use. And gives standard dialog box asking for either to close the application, or restart to complete updating.

Is there a way, eg. a custom action or a setting, to kill the processes running in the background so that the installer goes smoothly?
