Small correction: I meant to say, "we are going to ... create a dummy installer whose sole purpose is ... to prevent [the custom action DLL] from being removed when you UNINSTALL the first product." I.e., to make sure that it is still around when the post-RemoveFiles custom action tries to use it.
Also, theoretically you COULD try doing an in-place upgrade to the new version instead of uninstalling the old version and installing the new version as separate steps. But in the case of a defective previous-version installer and a clever workaround like this, I'd recommend keeping it simple and doing things one step at a time. It is possible that your custom action DLL may have additional dependencies on other installed files, in which case you will need to copy-and-paste their components into the dummy installer as you did before. If you need to do this, then you may need to make further adjustments to the custom action DLL to ensure that it is fully self-contained for use in subsequent versions (e.g., if it's a C# or VB.NET DLL, make sure you're using the one whose name ends with ".CA.dll").
