<!-- for jEdit: :mode=php:indentSize=2:tabSize=2:noTabs=true: -->

<p>To find out which Java virtual machine is best for running jEdit on
Windows,
see the <a href="index.php?page=compatibility">compatibility</a> page.</p>

<p>To install jEdit, simply double-click on the JAR file you downloaded;
the installer should start automatically.</p>

<p>If it doesn't start, then you will need to open an MS-DOS prompt
(<b>Start</b>-&gt;<b>Programs</b>-&gt;<b>MS-DOS Prompt</b>) and
enter the following commands:</p>

<pre>cd <i>directory where you downloaded the JAR file</i>
java -jar <i>filename</i>.jar</pre>

<p>For example, if you downloaded <code>jedit40install.jar</code>
into <code>C:\Downloads</code>,
you would enter:</p>

<pre>cd C:\Downloads
java -jar jedit41install.jar</pre>

<p>If for whatever reason
you want to start the installer in text-only mode, specify
<code>text</code> as the last parameter on the command line. In text only mode,
the installer will not display it's GUI, and instead it will ask
questions in the MS-DOS prompt.</p>

<p>Note that some Java versions for Windows have a bug where a JAR file whose
full path names contains a bang (!) will not run. If you get an error like
the following, try moving the installer JAR to a directory whose name does
not contain the bang:</p>

<pre>Exception in thread &quot;main&quot; java.lang.NullPointerException
