<p>Elrond Peredhil: </p> <hr /> <div>OpenRocket is a Java application - the reason that you need to know that is that some systems don't have Java installed.<br /> <br /> == General ==<br /> Here are the general steps you'll need to take. System-specific instructions are available below.<br /> # make sure you have Java available<br /> # [https://sourceforge.net/projects/openrocket/files/openrocket/OpenRocket-0.9.4.jar/download download] the OpenRocket application<br /> # open the application and use it<br /> <br /> == Windows Users ==<br /> 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.<br /> # [http://www.java.com/getjava/ download Java 6 JRE] from Sun<br /> # [https://sourceforge.net/projects/openrocket/files/openrocket/OpenRocket-0.9.4.jar/download download] the OpenRocket application<br /> # open the application and use it<br /> <br /> == Mac OS X Users ==<br /> 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.<br /> # open the Utilities folder (Finder -&gt; Go -&gt; Utilities) [[File:FinderOpenUtilities.png|none|200px]]<br /> # open the Java Preferences Application (double-click Java Preferences.app) [[File:UtilitiesJavaPreferences.png|none|200px]]<br /> # in the bottom section of the window that opens, drag Java 6 to top of list [[File:JavaApplicationPreferences.png|none|200px]]<br /> <br /> == Linux Users ==<br /> Some Linux distributions ship with Java, while others do not. Check to see if it is installed on your system. <br /> # make sure you have [https://sourceforge.net/projects/openrocket/files/openrocket/OpenRocket-0.9.4.jar/download Java] available<br /> # [https://sourceforge.net/projects/openrocket/files/openrocket/OpenRocket-0.9.4.jar/download download] the OpenRocket application<br /> # change permissions to allow the .jar to be executed<br /> # open the application and use it</div>
