	Base Upgrade from ver. 060504 to 060929 ONLY!	20.4 MB

• ZIP File: Download the basic distribution zip file if you wish to extract the files yourself.
• To run Orbiter you only need the basic distribution from either the web installer or the zip file.
• For installation instructions using the ZIP file, read HERE.
• The base package has no sound support, but there is a very popular sound addon by Dan Steph which we highly recommend. See more addons we recommend HERE

• Before downloading any of the extension packages, download and install the base distribution at the top of this page, and make sure it works correctly!
• To install a hi-res package, simply download to your main Orbiter directory and unzip. The files should end up in the Textures2 subdirectory.
• You don't need to download multiple resolution packages for a single planet. The higher-res packages already include all lower-res versions. The exception is Mars, where the L8 package must be installed in addition to any higher-res packages.
• If you install the Planets & Moons package, you don't need to install any of the packages marked with '*'.
• Installing the high-resolution packages can affect the simulation frame rates and loading times. They should be used with caution, in particular on low-end computers.

Software Development Kit (SDK)

The SDK package contains utilities and libraries for addon developers. It is not required to run Orbiter.
