Purchasing Celeste™

System Requirements

Celeste requires an Intel-compliant PC with Windows 95/98 or NT.

Purchasing*

Celeste costs $19.95. The simplest way to get the program is to download it from our website.

Whenever you run Celeste, you have the option to purchase a license.

  • If you choose to purchase a Celeste license, click on the "Purchase" button.   A secure order form will appear.  A license number together with instruction will be displayed after you enter the requested information.

  • If you do not purchase Celeste, you can use your copy five times before it expires. After five uses, you will be able to purchase on line, but the program will no longer run. It cannot be installed again as a demo on the same computer.

CD-ROM

We will send you a CD-ROM for $10 for shipping and handling. The program installed from the CD-ROM acts just like the one downloaded from this site.

You can install the demo version of Celeste on as many computers as you wish, but on any one computer it will only run five (5) times unless a license is purchased.  It cannot be installed as a demo twice on the same computer.

Order a CD-ROM from our secure server.

Installing on a computer not connected to the internet

If you install Celeste on a computer not directly attached to the internet, the program will generate a site-code for that computer. Please mail it  along with  a check drawn on U.S. bank for $20.95 ($19.95 + $1.00 for shipping and handling) to:

The DTN Group
P.O. Box 722336
San Diego, CA 92172

We will generate a license and mail it back to you. Until you enter the license, your copy of Celeste remains a five-use demo.

Volume Orders

If you wish to purchase more than 10 licenses of Celeste, please email sales@chemlearn.com.

Future add-ons

We are planning modules which will work with Celeste to augment its functionality.

*Appropriate sales tax will be added if required by law.
