I open the database and I get a message to download a 64 bit JRE, but it doesn’t indicate where to find it.
Addition to the FAQ: If you are on Mac OS X, the you need JDK (as per FAQ) and this can be downloaded from https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
Updated FAQ to include a link (to a parent page with version selection). Please feel free to improve FAQs - nobody knows frequent questions and answers better then those who helps people here. Thanks!
For Windows
