I now have this quite complete list of solutions:
- Google Omaha
- AdvancedInstaller
- Somoto BetterInstaller ( + adds recommendations from which you make money)
- Ignite (not available yet)
Or possibly create your own using the WiX Toolset, NSIS or Inno Setup.
All of those are free solutions, except for AdvancedInstaller. It has a free edition too, but cannot be used to create this package type; for this you need at least a Professional edition.
