All Euler sources and builds are distributed under the GNU general public license (GPL). The main point is that any modified versions remains freeware and open source and must be distributed with a clear reference to the original version. The idea is that the user should easily be able to find the original software on this site, if he uses your modified version.

Since there are now many sites offering collections of free software distributing old and very old versions of Euler Math Toolbox, I do no longer allow the direct download of my installation files from other sites (ask for exceptions). You are cordially invited to include Euler Math Toolbox in any software collection, but you must use the download link to this page. Please do not offer a public copy of the Euler installation on your site.

You may include Euler into collections distributed on CD or DVD, since it is clear that these media contains the version of the software available at the distribution date. You are still required to link to this page.

Other licenses are available on request.


I will not take responsibility for any damage Euler does to your data, files or computer, or any other damage. You use Euler on your own risk.
