Version 3 stable

To avoid problem of administrator rights, this version can be downloaded as a ZIP file (20 Mo)

To use the ZIP file, please extract the Casyopee directory into an allowed directory and run casyopee.exe.
It should run directly in English, and you can choose your language via  the Options Langue .menu.

Note that if the NotePad does not display correctly because of a restriction on the temporary directory, you can change it via the options.menu.

You can also use this version from an USB key.

Important: if using for the first time, please read the "Casyopee Getting started manual" (documentation downloads) or the online help ( also a menu entry on the website).

Looking at videos demonstrating Casyopée on Olivier Leguay's very exciting blog is also quite useful

Version 3.5.1 Correction bug on intersection. New Splash Screen.

Version 3.5.0 Numerous internal improvements, including redesign of the numeric evaluator and improvement of precision in the GD. Files prior to     version 3.3.0 are no longer loaded. Use version 3.4.6 for download on the site.

Version 3.4.9 Fix on fonc algo

Version 3.4.8 Environnement "sequences". User guide http://casyopee.eu/file/Lenvironnement_suite_de_Casyopee.pdf  (sorry French only)

Version 3.4.7 Numerical Evaluation enhanced. Approximate values' ​significant digits in the in the option menu. Points' labels move with the mouse. Variables declared in the algorithms are considered local.

Version 3.4.6 Corrections (modelling) 

Version 3.4.5 

Adaptation for Linux. Bug on geometrical calculations and formulas whose length exceeds 1024.

Version 3.4.4

Switch Radians/Degré. See here. Bugs on reported points.

Version 3.4.2

correction bugs (intersections, area between curve and line)

Version 3.4.1

correction bugs (modelling, comments in programs)

Version 3.4.0

Enhancement and localisation of the programming environment (function defined by an algorithm) after experimenting.

Option: Creation of functions with values in R² (parametric curves)

See documentation and examples of use in the on line Help

Version 3.3.6

finalisation of the programming environment (function defined by an algorithm)

To do: localisation and English documentation.

Bugs corrected in version 3.3.4:

1. loading functions with exponentials in .CAS files

2. saving and loading values of the variables in .CAS files

Bugs corrected in version 3.3.3:

1. parameters created automaticly

2. wheel in the graphic window

3. redefinition of points

Bugs corrected in version 3.3.2:

  about expressions (updating and saving)

Bugs corrected in version 3.3.1:

1. modification of properties of parameters: Casyopée issues a warning, most of the time irrelevant, when the parameter is used in the fomula of a function. In this case please simply ignore and confirm.

2. problem of display of geometrical loci. 

Casyopée Upgrade latest version.

Automatic update works from version 3.2.6.

This is the "by hand" procedure for previous version 3.

Download the file maj.exe into the /casyopee3 directory (where casyopee.exe is).
If you want to keep the existing version, rename casyopee.exe into casyopee_old.exe.

run maj.exe

In case you did not rename casyopee.exe, you will be prompted to confirm replacement.

In case you do not want to keep the previous version, you can erase the directory V_3_y_x  

Run casyopee.exe as usual.
