InstallAware Software has ported InstallAware for Windows Installer to macOS and Linux. Powered by its Native Engine (no MSI files outside of Windows), InstallAware Multi Platform strives to make the transition as easy for you as possible:
o If you're an existing InstallAware user, just load and recompile your existing projects. All your scripts, localizations, and custom dialogs work seamlessly on your new platforms. We've written a lot of code to ensure your existing installations run as intended on your new macOS and Linux targets - compiled virtually, if not literally, verbatim!
o If you're new to InstallAware, we try to anticipate and bridge the conceptual chasms which you would need to be crossing as a part of the porting. For instance, our Create File Type command implements and registers a shim application on macOS which launches your actual handler, passing the opened file as your application's first command line parameter. That's not quite how it normally works on macOS, but that's the point.
