We are working on evolving our products to new formats of distribution e.g. Virtual Machines or Docker containers. This helps us to unify our code base for different platforms and focus our resources on improving all the solutions in the catalog. We plan to keep most popular installers for development for Windows but unfortunately ELK was not in that list.
Even we support Docker containers and Virtual Machines for Linux platforms, we are working on an alternative for Linux installers that would provide a similar user experience than the previous installers.
I'm sorry this may cause you troubles in the short term, but we believe this is the way to go, and that this will be the best solution in the mid term.
