Yes, product is active and we should release 4.9 version in a matter of days. Web Platform Installer package was removed because of some issues that Microsoft reported back to us, they were fixed but we wanted to wait until we have 4.9 version ready for release so we will push the package soon.
You can always download the package from our download section
and give it a try. Feel free to get back to us if you run into any issues.
