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.

For Windows users, the default installation folder is c:\Program Files. In Windows 10, and possibly other versions, a non-admin user might not be able to run Simredo from c:\Program Files . In that case, install the program in a different folder, 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.

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.
