Security

I don't know the app at all but my suspicion is that the message box you're seeing is created by a function called by a Custom Action, in which case it's extremely unlikely you can control it. The alternative is to create a transform which doesn't call that CA. That obviously means that you need to duplicate its functionality in the transform.

BTW, your question may have been answered earlier if you had posted it in the Package Development forum.

Thanks VBScab! [:D]

Did you want to let us know what the outcome was, for anyone coming here in the future?

I referred this back again to my co-worker who also QA'ed it. We searched and searched and decided to leave it be. The business unit wasn't concerned that it would pop-up to ask the user when the uninstall runs. Overall, we decided that the time we would spend on figuring out the solution for something like this isn't worth it - we have many apps we need to package but I do plan on going back to it to figure it out once things slow down just to learn more from it. I've only been packaging for 4 months and this is the second package I've ran across that we just couldn't silence. I guess you run across those every once in a while. Thanks again for your input!
