OmegaT can be installed on any operating system capable of running version 1.6 of the Java runtime environment.
The "batteries included" version of OmegaT, with its own Java Runtime Environment. This version will take longer to download and will require more space on your hard drive, but you can be confident that it will run. If in doubt, select this option.
The included JRE is the 64-bit version.
The "batteries included" version of OmegaT, with its own Java Runtime Environment. This version will take longer to download and will require more space on your hard drive, but you can be confident that it will run. If in doubt, select this option.
If you are sure that a suitable Java Runtime Environment is already installed on your computer at system level, you can select the option without JRE included.
The "Standard" version of OmegaT includes a full user manual (at least in English) and will usually have been tested for some time to eliminate any bugs. It is the recommended version for first-time users.
OmegaT will run on any system on which the JRE (Java Runtime Environment) has been or can be installed. The JRE is now supplied with OmegaT and need not be obtained separately. OmegaT has been successfully installed on Windows (all versions from 98 onwards), macOS and Linux.

You can still find older, superseded versions of OmegaT.
Legacy versions are older versions that have been superseded. For most users, these are not of interest. However, some users may face restrictions (imposed by their operating systems or Java version) that may result in a preference for an older version.
In order to run, OmegaT requires the Java Runtime Environment (JRE) to be installed on your computer.
If you are confident that a suitable version of the JRE is already installed on your computer, you can download a version of OmegaT without the JRE. The download will be faster, and the installation will require less space on your hard drive. In this case, do not select the Default version; select a different version (e.g. Standard or Latest), then select a version marked "Java not included".
If you install the OmegaT version with JRE even though the JRE is already installed on your computer, OmegaT's JRE will be installed separately and will not conflict with it. It is therefore always safe to install the version of OmegaT with JRE. If you are unsure whether or not you have a suitable version of the JRE, select a version with JRE (or the Default version).
macOS users: the JRE is installed on macOS by default; there is therefore no version for macOS with the JRE.
Linux users: most Linux distributions are supplied with a Java Runtime Environment, but some open-source implementations do not work properly with OmegaT (although this may not be immediately apparent). If you are relatively new to Linux, we advise you to select an OmegaT version with the JRE included. More experienced Linux users may prefer to install the Oracle (formerly Sun) JRE at system level.
