Simredo runs on version 1.6 and higher of the Java Runtime Environment. In new computers, JRE is usually pre-installed. Please refer to Requirements for details.

Simredo has an installer program called SimInstall.jar. The first step in the installation process is to click on this link. The next few steps depend on your operating system:  Mac  Win  Linux

For Mac OS X Users

Clicking the above link downloads the installer to your download folder. This file cannot be run with a double click; do a control-click (hold the control button down while clicking on the file), and select 'Open' from the pop-up menu.

For security reasons, the operating system will display a warning dialogue. If you are confident about the source of this file, click on 'Open'.

For Linux Users

After clicking on the above link, a dialogue similar to the one at right will appear. Click on Save File to download the installer.

When the download is completed, a 'Downloads' window, like the one at right, may pop up. Close this.

The Installer

When the installer starts up, it will display a dialogue similar to the one shown here.

The default installation folder (in blue) can be changed with the Dir button.

In Windows XP, the OS which will never die, the default installation folder is c:\Program Files. In some versions of Windows, a non-admin user does not have privileges to install into c:\Program Files . In that case, select a different location, perhaps c:\ .

There are two checkboxes: 'Install the program' and 'Make a shortcut.' The 'Install the program' option should be checked. (This was made optional for testing purposes.)

If the 'shortcut' option is checked (highly recommended), the installer will put a shortcut on the desktop.

Click on 'OK' to install the program.

The installer will create a subfolder called Simredo4 ( in Mac OS X), and copy the executable jar file, Simredo4.jar, into it. In addition, it will create a subfolder called 'simredo' to hold parameter files, keymap files, conversion table files, and dictionary files. The parameter files are described below.

The installation should only take a few seconds. When it's done, a 'Finished' message will briefly appear.

About the Mac Shortcut

In Mac OS X, the desktop shortcut is actually a tiny app called SimLauncher, which starts up the main app.

About the Linux Shortcut

In Linux, after the installer finishes, the desktop shortcut may appear as shown here.

If you see this, do a right button click on the shortcut, and select Properties. In the Properties menu, go to the Permissions tab, and put a check in the Execute checkbox, as show below at right.

The shortcut should now display correctly.

Starting the Program

The easiest way to start Simredo is to double click on the desktop shortcut. If you did not create a shortcut, there are other ways to start the program: Mac users can double click on the application folder (; Windows and Linux users can double click on the executable jar-file Simredo4.jar, in the folder Simredo4.

It's also possible to start the program with a command line.

In Linux, open up a Terminal window and type:
java -jar Simredo4/Simredo4.jar
In Windows, open up a Command Prompt window and type:
java -jar Simredo4\Simredo4.jar

When Simredo starts up for the first time, it will ask which language to use for menus and messages. After you select your preferred language, Simredo is ready to use.

Parameter Files

There are three parameter files in the folder 'simredo'. They are:

simlang.txt -interface language: English, Esperanto, French, Greek, Hindi or Sorbian
simlist.txt -list of up to 16 previously edited files
simfont.txt -various parameters: font name, font size, keymap, etc.

simlist.txt and simfont.txt are 16‑bit Unicode files. simlang.txt is an 8‑bit file.
