OCHRE requires Java 8, and expects a 64-bit operating system and at least 4GB of RAM by default. It is available under Windows, Mac OS, and Linux. Note that the default Java installation is often the 32-bit version. If you are using a system with a 64-bit processor, Uninstall the 32-bit version of Java and use the 64-bit version appropriate to your operating system instead.

The default Start OCHRE link requires a 64-bit operating system, the 64-bit version of Java (which will list “64-bit” under your Control panel’s Programs) and at least 4GB of RAM, as do the other available Themes which offer variations in the “look-and-feel” of the OCHRE interface. All startup links provide the same functionality.

If your computer has a 32-bit processor, or less than 4GB of RAM, or has an extra-high-resolution (DPI) screen, select the appropriate Alternate Version for starting OCHRE.

The Start OCHRE link will download a jnlp (or jsp) file which should launch Java. If your browser does not know what to do with a “.jnlp” file you may need to associate this file type with “Java Web Start Launcher” using the browser’s file association feature.
