Java Runtime Environment

To run an x.factory librarian you will need the Java Run Time Environment (JRE) Version 7 or a later compatible release, installed on your computer.

Don't panic about this need for Java. Quite a few applications use it these days, and installation via the Oracle website link given below is no more difficult than installing any other application.

IMPORTANT NOTE: x.factory librarians are not currently compatible with Java 9 due to some major platform changes in Java 9. I will address these issues as soon as possible. In the meantime please remain with either Java 7 or Java 8.

If you don't already have Version 7, or a later version, of the JRE installed on your computer, which is unlikely unless you are already running Java Applications, then you will need to download and install a copy of the JRE, which you can do by following the Get Java Software Link to visit Oracle's Java download site.

Whilst JRE Version 7 is the minimum version of Java required, Version 8 is recommended.

If you have a 64 bit version of Windows then download and install the 64 bit JRE, which provides much better performance than the 32 bit JRE.

Mac OS X Users, please note that Apple no longer provide or support Java as a built in component of OS X. Support and development is now provided by Oracle. Apple Java 6 is now no longer supported or installed by default. I have also elected to make the minimum Java version to be version 7 as it provides additional features that make programming simpler.
