Help using installshield

I need help with installshield (latest version) I have software that I want to deploy using the installshield SMS technology and will pay for advice on how to package the product properly. My current initial install works properly but updates insist that the DLL versions are differant and mine are often the same. I am willing to pay for help on an ongoing basis until the project is done. We are talking .net assemblies that need to be registered both in the GAC and also in the registry (eg using REGASM). thanks ## Deliverables help and advise only needed ## Platform must be top notch installsheid person
