Euler comes with a simple installation file EulerSetup.exe. This is an installation program for Windows which has been created using InnoSetup. It works for all versions of Windows so far.
The installation will create the following things on your computer
The user can save notebooks and other files to the "Euler Files" directory. Euler does not write or read to this directory by itself.
Euler will also use a folder named "Euler" in the user home folder (Usually C:\Users\Name). This is used for intermediate Euler files (Press F9 or F10 in an empty line), for Maxima gnuplot, for Povray files, or for Latex files.
If you uninstall Euler, the Euler installation directory will be removed, as well as the association of Euler files. Your "Euler Files" folder remains intact, as well as the temporary folder "Euler" in the user home.
Also the settings in the registry are not cleared, since users might want to reinstall a new version of Euler with the same settings. These settings take only very little space.
If you need Euler on a stick, or do not want to install Euler into your system, you can create a version that does not alter the computer.
To install Euler on a USB stick, do not simply change the installation directory. You would still get icons and uninstall information on the computer pointing to data on the stick. Instead, do the following.
To install Euler in a local network, you need to provide a place for the Euler binaries on the file server, and another place for the user home directory and the Euler configuration in the home directory of the current user.
If you select the full EulerSetup.exe, Maxima will be installed into the installation directory of Euler.
If you select the installation without Maxima, you need to install Maxima on your own. You can link Euler to your Maxima installation. As long as Maxima does not change its interface, this will work just like the full installation.
To link Euler to Maxima, open Options / Symbolic Setup / Setup Maxima ... You need to browse for the maxima.exe file, and the Maxima directory.
Gnuplot in Maxima uses the "Euler" directory in the user home file.
Euler can display formulas formatted by Latex in comments or as command output (see here). For this, a version of Latex must be installed. I recommend installation MikTex. by default, Euler uses the AMS package. So you should install this too.
After the installation, you can put the Latex executable into the path in the system environment (for an alternative, see below). To do this open the System Settings of Windows, and search for Environment. Once you have opened the dialog for the environment variables, create a new variable named "Path" for the user, or edit the existing variable. Append the path to latex.exe (seperated by ";" if there are other items in the path). For MikTex this will be something like
c:\Program Files\MiKTeX 2.8\miktex\bin
You can check this setting by opening a command window (type cmd in the start menu), and trying to execute
latex -version
Alternatively, you can browse for Latex in Options / Latex Settings / Setup Latex ... You need to tell Euler, where the latex.exe and the dvinpng.exe are. The default position of the working directory is "Euler" in the user home. You can leave this blank.
Euler can call the open raytracer Povray to generate photo-realistic 3D output. You need to install Povray from their site. During the installation, write down the path to the installation directory.
There are two ways to link Euler to Povray. The first way is to add the path to Povray to the environment. Open the system editor for environment variables as described in the section about Latex. In installed Povray installed into
C:\Users\Rene\Povray\bin
So add this to the path as described in the section about Latex.
Alternatively, you can set the Povray engine in each notebook that uses Povray. You need to do this using an Euler variable.
defaultpovray = "C:\Users\Rene\Povray\bin\pvengine.exe"
The default values is "povengine.exe". This executable will only be found, if it is in the path. This is the preferred way to install Povray.
Povray writes intermediate files and the PNG output to the "Euler" folder in the user home folder.
The Windows version of Euler will run under Wine with many restrictions. For details on this, refer to this document.
