OpenRocket is a Java application - the reason that you need to know that is that some systems don't have Java installed.

General

Here are the general steps you'll need to take. System-specific instructions are available below.

  1. make sure you have Java available
  2. download the OpenRocket application
  3. open the application and use it

Windows Users

The installation is the most difficult because Java doesn't automatically ship with Windows. You may already have Java available because lots of other apps are built on it (i.e. virus scanners, other open source software, etc.). If you don't have Java on your computer already, then you'll need to download it from Sun; it is free.

  1. download Java 6 JRE from Sun

Mac OS X Users

Apple sends out Java with system updates. A common complication with Mac users is that most Mac's have Java 5 and Java 6 installed and Java 5 is the default. If you try to use OpenRocket and get an error, then you probably have Java 5 as the default still.

  1. open the Utilities folder (Finder -> Go -> Utilities)
