What is the lifespan of the CustomActionData variable? We have some values pushed into it. During one of our Execute sequence CA's (after RemoveODBC) the values are present. During the next CA (after DuplicateFiles) the values are gone. We're using Chris Painter's MsiGetCustomActionDataAttribute() to decode the string. I've added a MessageBox to display the entire buffer just to verify what's in there at a given point. Either the value is getting clobbered during the Execute sequence or we're trying to use it after it's been disolved.
CustomActionData is scoped per deferred custom action. That means you need to have one immediate custom action that sets up custom action data for each deferred custom action that needs to access CustomActionData.
