There are several possible ways to check your Java version on Windows.

From the Windows Start menu

Once the download completes, navigate to the folder where the ZIP file was downloaded. On a Windows machine, this will typically be your "Downloads" folder, e.g., "C:/Users/<your-username>/Downloads".

Right-click on the ZIP file and choose "Extract All..." from the context menu to launch the Extract Compressed Folders dialog. Click the Browse... button to select a destination for your Protege Desktop installation, e.g., the "C:/Program Files" folder:

Linux and Unix-like

Protege 5.0 is distributed in the form of a tar.gz file and requires Java 7 or later.

Please consult the documentation for your Linux distribution on how to install Java. Usually, you can install Open Java easily from the package manager of your Linux distribution (e.g., apt-get in Ubuntu and Debian distributions, yum in RedHat ). You may also use other Java implementations, such as Oracle Java. For Ubuntu, you can find the installation instructions for different Java implementations here. For RedHat, the installation instructions for Open Java are here, and for Oracle Java here. General Oracle Java installation instructions for Linux distributions are here.

Check for Java 7 (optional)

This step is optional. Perform this step, if you are not sure if you have Java 7 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 "1.7.0_51"
 OpenJDK Runtime Environment (IcedTea 2.4.4) (7u51-2.4.4-0ubuntu0.13.04.2)
 OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)

(The version should be 1.7 or later)

Download the tar.gz file

• Go to the Products page on the Protege website.
• Click the "Download for Linux" button to download the tar.gz file to your machine.

To unpack the archive, either use your file explorer and double-click on the archive, and extract it to the desired location, or type in a terminal window:

tar zxvf protege-5.0.0-beta-06_2014_05_20.tar.gz

(the archive name might differ, please use the right file name that you downloaded.)

Launch Protege

To launch Protege Desktop, double-click on the run.sh in the Protege folder in the file explorer, or type run.sh in a terminal window, once you have changed the directory to the Protege folder (cd Your_Protege_folder).

Troubleshooting

Q: When I double-click on the run script, nothing happens, or I see a window that comes up, and goes away!

A: Try to run Protege from a console window and report back on the protege-user mailing list the errors that show up in the console. In Windows, to start a console window, click on the Start menu and type cmd in the search box, then in the console, change the directory to where you unzipped Protege (for example, cd "C:\Program Files\Protege_5.0_beta"), and then type run.bat. To start a terminal window on Mac OS X, go in Finder -> Applications -> Utilities -> Terminal.

Q: When I try to run Protege with the run script, I get a UnsupportedClassVersionError, something like: Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file

A: Most likely you have an older Java version installed. You need to have at least Java 7 or later installed to run Protege desktop. Please see the documentation above on how to check which version of Java you have installed.

Q: The Protege UI freezes occasionally on Linux with Open Java. Protege still seems to be running (CPU at normal levels), but I cannot click on any of the entities, tabs or menus.

A: There is a bug in Open Java on Linux distributions (e.g., Ubuntu) with parentless dialogs that will cause this behavior. The workaround is to use another Java implementation, like Oracle Java.
