I have moved away from the Rhino Installer Engine, because we have about 10 plug-ins or so, that use a number of shared DLL’s. This would lead to the user having to install each plug-in separately, which was experienced as a hassle.
Instead, I have created a Windows MSI installer using WiX, which deploys all plug-ins and support DLL’s in one action. By making sure that it does not need administrator priviliges, the users can install updates by themselves.
Going from no experience with WiX and MSI creation to a working installer took me about two days, and I haven’t look back since.
