Download and Installation

Available downloads are:

On SourceForge On GitHub

Installation:

Prerequisite, Java must be available:
Java is open source and can be downloaded from https://adoptium.net.
SQuirreL will always run with the current LTS (Long Term Support) release of Java.
The minimum Java version required usually is the previous LTS release.

Installation of the SQuirreL SQL Client on Windows and Linux/Unix:
The SQuirreL SQL Client can be installed by the IzPack installer. Download the file squirrel-sql-<version>-standard.jar and execute it using the following command:
java -jar squirrel-sql-<version>-standard.jar    when you properly installed Java.
or
<path to Java directory>\bin\java -jar squirrel-sql-<version>-standard.jar    when you just unpacked the zip or tar.gz version of Java.
Note: On Linux/Unix replace backslashes (\) by slashes (/).

Make sure that you have write privileges to the directory that you want to install into.
Note that some browsers may attempt to open this file rather than download it. In this case, right-click on the download link and click your browser's equivalent of the "Save as..." menu item.

Installation of the SQuirreL SQL Client on MacOS:
On MacOS the preferable way to install the SQuirrel SQL Client is the MacOS X installer squirrel-sql-<version>-MACOSX-install.jar.

Starting the SQuirreL SQL Client:
On Windows, execute the file squirrel-sql.bat to run the application. On Linux/Unix and MacOS, the file is squirrel-sql.sh.

Trouble shooting:
When SQuirreL SQL doesn't start:
On Windows try to add the line
  set JAVA_HOME=<path to Java directory>
to the top of squirrel-sql.bat
On Linux/Unix or MacOS try to add the line
  export JAVA_HOME=<path to Java directory>
after the line
  #! /bin/sh
of squirrel-sql.sh

Scaling problems on high resolution screens:
Set the JVM (Java Virtual Machine) parameter
-Dsun.java2d.uiScale=<scaleValue>
Example: -Dsun.java2d.uiScale=2.5
This can be done by editing squirrel-sql.bat on Windows and squirrel-sql.sh on Linux/Unix or MacOS
or by setting the SQUIRREL_SQL_OPTS variable before executing the start script.
