Protege 5 Installation instructions (Platform-Independent)

Go to the main Protege 5 installation page

The platform-independent archive contains the Protege software, including the run scripts to launch Protege on any platform. It does not include the Java Runtime Environment (JRE), so you must have a working Java installation on your machine prior to using this archive. Also, the platform-independent archive will work with older 32-bit machines.

The required Java version is 8 or newer.

If you have Java 8 or newer on your system

Then, it's very easy:

• Download the platform-independent archive from the main Protege website. The link is under the platform-specific download button, and it is called: Download platform independent version.
• Run the appropriate run script for your platform (e.g., run.bat on Windows, run.sh on Linux and run.command on Mac OSX).

Note: You may need to adjust the java path in the run script.

If this does not work, read more in the section below corresponding to your operating system.

Also, read more on the installation instructions for your platform from here.

This step is optional. Perform this step if you aren't sure if Java 8 or later is installed on your computer.

Troubleshooting

Q: When I run run.bat in Windows, I get the error message:

'java' is not recognized as an internal or external command, operable program or batch file.

A: Windows cannot find Java on your system. This can happen either if: (1) you do not have Java installed on your computer, or (2) you have Java installed, but it is not found on the PATH environment variable of your system.

Mac OSX

Check for Java 8 (optional)

This step is optional. Perform this step if you aren't sure if Java 8 or later is installed on your computer, and used by the Terminal application.

• Open Finder.
• Go to Applications -> Utilities.
• Double-click the Terminal application.
• At the prompt, type "java -version" to see your Java version number:

Linux

Check for Java 8 (optional)

This step is optional. Perform this step, if you are not sure if you have Java 8 or later installed on your computer.

To check that you have Java installed, open a terminal window, and type: java -version. You should see something like this:

 myuser@mycomputer:/$ java -version
 java version "1.8.0_91"
 Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
 Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)

(The version should be 1.8 or later)
