Upgrade Sequence Control with Basic MSI

[csturtz]

I have a Basic MSI project. I need to add a new screen that just displays some text to the user, but I only want this screen to show up during an upgrade. How can this be done?

Thanks

Please see the following newsletter tip regarding how to do this for a major upgrade; you can use the same idea for a minor upgrade, but the condition will be different (PDF): http://www.flexerasoftware.com/webdocuments/PDF/nl_article_DEV_MajorUpgradeUI.pdf.
