== Upgrading an old installation ==
 
If you have downloaded Fiji or ImageJ2 quite some time ago (before 2016), you probably have the Java 6 version. So when you update, you will not receive the latest plugin releases anymore, as described above.
 
To upgrade to the Java 8 version and receive the latest updates, you have two choices:
 
# Download a new Fiji as described above; or
# [[Frequently Asked Questions#How_do_I_launch_ImageJ_with_a_different_version_of_Java.3F|Switch your current installation over to Java 8]], and ''then'' enable the Java-8 update site.
 
'''''If you enable the Java-8 update site while still running Java 6, your installation will become non-functional''''''!
