Okay, I've now wasted far too long trying to get this working. I am trying to run a CA on uninstall (my co-workers jokingly suggested that it's unnecessary, since no one would EVER want to uninstall our product), and no matter what I do, it won't work. I've tried the following conditions:
_IsMaintenance = "Remove"
and
&FeatureName=2
Regardless, this always evaluates to false. Logging the uninstall turns up this:
MSI (s) (B8:34) [15:37:59:241]: Skipping action: UninstallService (condition is false)
Am I in the Twilight Zone? Are all uninstalls really installs now? What's going on with this?
Where in the sequences does your action occur? If the Execute sequence (which it presumably is, since it makes a system change), the private property _IsMaintenance will be reset to its default value when execution switches from the UI sequence to the Execute sequence. Please see this old newsletter tip for more (PDF warning): http://www.acresso.com/webdocuments/PDF/msiconditions.pdf.
Oh, that did the trick! Thanks... I wonder why I don't have more of these documents. I also wish I had saved more of my projects from my last job for use as personal references, where I had plenty of things like this working already.
