There are two ways of installing WUDSN IDE. Precondition for both is that you have Java 1.6 or newer already installed on your
system. If you are using a Windows operating system, I recommend downloading the ready to run zero installation distribution:
<br/>
<div align="center">
	<a href="http://www.wudsn.com/productions/java/ide/downloads/wudsn-ide-win32.zip" target="_blank">
		<img src="productions/java/ide/installation/ide-download-win32.png" alt="Click to download the Windows 32-bit version"/></a>&nbsp;
	<a href="http://www.wudsn.com/productions/java/ide/downloads/wudsn-ide-win64.zip" target="_blank">
		<img src="productions/java/ide/installation/ide-download-win64.png" alt="Click to download the Windows 64-bit version"/></a>
</div>
It contains the Eclipse Platform, the latest stable version of WUDSN IDE plugin, all supported compilers and an emulator for
each supported platform. All paths to folders, compilers and emulators are pre-configured. Unpack the content of this archive to
the directory "C:\jac\wudsn" and click the "WUDSN IDE" link. Eclipse will open with the predefined workspace that contains
"Hello World" examples for different platforms.
<br/>
<br/>
If you use another operating system, or want to use the latest version of WUDSN or want to install compilers and emulators more
selectively, read the descriptions of the installation steps below.In case something is not correct or not working, please

<ul>
	<li>
		Download Eclipse from
		<a href="http://www.eclipse.org/downloads" target="_blank">http://www.eclipse.org/downloads</a>
		.
	</li>
	<li>
		If you don't know which version to take, use
		<a href="http://download.eclipse.org/eclipse/downloads/drops4/R-4.3.2-201402211700/#PlatformRuntime" target="_blank">Eclipse 4.3.2
			Platform Runtime Binary (61 MB)</a>
		.
		<br/>
		This is a minimum size installation which does not include the Java Development Toolkit (JDT). WUDSN IDE has no dependency to
		the JDT but of course to the Java Runtime Environment (JRE). Make sure you also have the 64-bit version of the JRE installed
		if you want to use the 64-bit version of Eclipse.
	</li>
	<li>Unzip the downloaded archive file and store the contained folder "eclipse" where you want Eclipse to be located on you
		local hard drive.</li>
	<li>Start the Eclipse executable from that folder.</li>
	<li>Upon the first start you are prompted to specify the folder where the workspace shall be located.</li>
	<li>Normally a start link a created to this end. You can use the parameter "-nl" to specify the locale if you want. Use "en_US"
		for English or "de_DE" for German. Example: "C:\Program Files\Eclipse\4.3.1\eclipse\eclipse.exe" -Xmx512M -nl en_US"</li>
	<li>It is recommended to create the workspace folder in your home directory.</li>
	<li>After you have read the welcome page and got familiar with the Eclipse UI, just switch to the Resource perspective.</li>
	<li>
		Open the view "Problems" via the menu "Window/Show View/Problems" and then click the entry "Configure Contents..." from its
		view menu.
		<br/>
		<img src="productions/java/ide/installation/ide-problems-view-01.png" alt="Open configuration of the problems view"/>
	</li>
	<li>
		Select the configuration "All Errors", the radio button "On selected element and its children" and the check boxes ""Error",
		"Warning" and "Info".
		<br/>
		<img src="productions/java/ide/installation/ide-problems-view-02.png" alt="Configuration of the problems view"/>
	</li>
	<li>
		Now Eclipse itself is ready and you can proceed with step

<ul>
	<li>Start Eclipse</li>
	<li>Select the entry "Install New Software..." from the menu "Help".</li>
	<li>Enter "http://www.wudsn.com/update" in the "Work with" field and press ENTER.</li>
	<li>
		Select the latest version of the feature "WUDSN IDE" for in and press the button "Next".
		<br/>
		You don't need to install the "General Eclipse Enhancements" feature as it is already included in the "WUDSN IDE" feature".
	</li>
	<li>Review the installation details and press the button "Next".</li>
	<li>Read the license agreement, choose the option "I accept..." and press the button "Finish".</li>
	<li>In case you get a security warning that the content is unsigned, confirm the warning by pressing the button "OK".</li>
	<li>When you are prompted to restart Eclipse now, press the button "Yes".</li>
	<li>
		As always with updates, it may happen that the update fails for whatever reason or the installed version turns out to have
		severe issues. For example the required Java Version might not be available on your machine. In this case you can uninstall it
		via the link "What is already installed" in the "Install New Software..." dialog and restart the IDE. Then you can reinstall
		the latest version from "http://www.wudsn.com/update" or previously released versions from the locations listed in the
		"Releases" chapter.
