ImageJ2 will run on any system that has a Java 6 (or later) runtime installed. This includes, but is not limited to:
- Windows XP, Vista, 7 or 8 with Java installed from java.com
- Mac OS X 10.5 "Leopard" with an Intel 64-bit processor with the Java 6 update
- Mac OS X 10.6 "Snow Leopard" (Java 6 is preinstalled)
- Mac OS X 10.7 "Lion" or later with Java installed from java.com
- Ubuntu Linux with sun-java6-jre or openjdk-6-jre installed from the package manager
Please note that we currently test ImageJ2 mostly with Oracle Java 6. We have done a limited amount of testing with OpenJDK and with Java 7, and things superficially work, but there may be additional bugs in those cases. Feel free to report any such issues to the mailing list.
In the future, we hope to support systems with only Java 5 or earlier available (such as older versions of Mac OS X on PPC), via the use of the Retrotranslator library. We also plan to install or bundle Java automatically as needed. But there are unfortunately many higher priority tasks first.
The latest release of ImageJ2 is v2.0.0-beta-7, released on June 11, 2013.
Please note that this is BETA-QUALITY code, unfinished and subject to change as development continues.
