InnoScript will be supporting Windows Side-By-Side installation creation (WInSxS). This will allow one to create an installation where you do not need to register COM dll/ocx/exe files. This will allow different versions of the same files to be on a computer and not be concerned about DLL Hell. The COM file deployed will be in your app's folder with a manifest that will allow them to load and not conflict with other files that maybe registered on the computer.
