Medicare Online requires Java 6 to work.
Java 6 will be installed when you run a Medilink Update.
However, if you update your Java, it will automatically remove old versions of Java unless you tell it not to. For most of our practices, this happens when ATO software is updated (because the ATO requires Java 8).
If your Java 6 is removed, Medicare Online may appear to work initially, but then parts of it will fail. In this case you should be prompted to re-install it and/or you can manually re-install it by running:
(Depending on your Medilink install location.)
Note that Java 6 is not a Medilink requirement, this is Medicare's own requirement. We don't have much control over what your other applications or operating system does about Java, so you will have to be careful when it does update to avoid removing Java 6.
