[wix-users] Advice on an upgrade...

[Steve Ogilvie]

Hi folks,
Version 1 of our product (which has gone out the door) installs a MSI for a bunch of plugins, as well as our product MSI (so 2 MSI's).
Version 2 of our product (which hasn't been released yet) had merged the files from that MSI, into our product MSI.i.e. the 12 files from the plugin MSI are now in our product MSI.
I tested an in place upgrade of Version 2 overtop of Version 1, all works well EXCEPT that the Plugins MSI does not get uninstalled and remains behind.
Any idea on how to safely uninstall the Plugins MSI on upgrade with version 2?
Thanks,
Steve
