I implemented Custom Action DLL that needs to run when the product is being unistalled or reinstalled. Custom Action DLL (C++) references third party library which is a COM object that needs to be also registered.
I have 2 questions: 1. How do I include third party library into installer package? I'd prefer if the file were not visible to the user. 2. How do I make sure that 3rd party library is still around when Custom Action DLL runs during unistall? CustomAction is run before 'InstallFinalize'.
