The WiX custom actions perform their install/uninstall actions on a
per-component basis by calling MsiGetComponentState. If the resource is
currently installed locally or to run from source, and the action is to make
it absent or removed, the uninstall tasks are performed. It's probably a
good idea to stick to this model.
You can also query whether a feature is being uninstalled using
MsiGetFeatureState.

Subject: [WiX-users] Question about writing custom actions...
...how do I tell if I am uninstalling a product or installing it? We have a
library we've written to do some configuration changes, but now we want to
different things when a user installs and when a user uninstalls. I poked
through the MSI SDK, but nothing really jumped out while skimming the CHM
file.
Thanks!
Rory
