J systems are available for a number of platforms and can be installed and redistributed for free.

The 64 bit distributions have 64 bit integers, a 64 bit address space, and run on Windows, Linux and OSX 64-bit systems. The 32 bit distributions have 32 bit integers, a 32 bit address space (limited further by the OS), and run on both 32 bit and 64 bit systems.

J and the Qt desktop have been tested and are supported on the following platforms:

  • Windows 32 - XP or later
  • Windows 64 - 7 or later
  • Mac 64 OSX - 10.6.8 or later
  • Linux 32/64 - Red Hat 6 or other distribution with Qt 4.8 (most popular distributions)
  • Raspberry Pi - any version with Raspbian OS

J is also available without the Qt desktop on:

  • Android - 2.3.3 or later

Note: both Windows XP and OSX 10.6.8 are no longer supported by their vendors and no longer receive security updates. Future support of J on those platforms is not guaranteed.
