EUKLID DynaGeo is shareware.
It is distributed in a compressed archive file via the Internet. If you want to give EUKLID DynaGeo to any other person, you can make copies of the original archive and pass them on. But in general it's easier just to indicate the URL of the english EUKLID DynaGeo pages: http://www.dynageo.com.
What's the price of a license?
You may use the program for 8 weeks to test its suitability. If after this time you want to continue using EUKLID DynaGeo, you must buy a license. The use of the shareware version in schools and similar educational establishments is strictly prohibited.
Registered users receive their personal license data to convert the shareware to a licensed version. The license comes to you as a small file attached to an email that I'll send to you. The license file has the name extension ".DGL" (what means "Dyna Geo License"). For security reasons, it may be zipped, so you must unzip it first. Then just copy the DGL file into your DynaGeo folder, where the installation program has written the DynaGeo.exe to (normally "C:\program files\DynaGeo\"). With the next start, DynaGeo will come up as fully licensed program.
As the English version of EUKLID DynaGeo is distributed exclusively via the Internet, I presume that everyone buying a license will download the program from the Internet. I shall not send any media around. Moreover, there is no printed manual. The only documentation is the program's built-in help, and I hope this will be sufficient.
EUKLID DynaGeo has been developed mainly for educational purposes. So there are 2 different sorts of license:
What about updates?
A single user license costs EURO 25,- + VAT
and allows the use of the program within the usual conditions (on one computer at a time, similar to the use of a book).
An extended school license costs EURO 125,- + VAT
and allows not only the use of the program on all computers and networks within the school, but also on the private computers of all teachers and students of that school.
For users outside the European Community, no VAT will be charged.
When you order a licence for EUKLID DynaGeo 2.5, then you'll get all updates of the "2.x" series for free: just download the new installation archive from the download page and install it "over" your existing licensed version of DynaGeo! With the next start, DynaGeo will come up updated and licensed.
Limitation of liability
If the main version number augments due to bigger development steps of the program, then you may need a new license. This is offered to you at a reduced price. For further details, please go to the Order & update page.
