Tethys uses freely available software and may be installed and modified freely.   There is nothing that in principal would prevent it from being installed on Linux or MacOS, but as most of our user community uses Windows we are currently concentrating our efforts on developing Windows installers.

Windows Installation

What should I download?

Tethys can be installed for either 32 or 64 bit architectures.  It is highly recommended that if at all possible the 64 bit version be installed on the server machine as there are limitations to 32 bit programs that can prevent the processing of large data sets. As of version 2.3, 32-bit Tethys is no longer being supported.  To use the 64 bit version, you must have a 64 bit version of Windows. If you wish to add data to Tethys that is stored in Microsoft Office format (e.g. Excel, Access), the server machine must either have Microsoft Office installed or a freely available driver from Microsoft (details are in the Tethys manual).   If a 32 bit version of Office is installed, the 64 bit server will not work and vice-versa.  As Microsoft does not currently permit 32 and 64 bit Office drivers to be installed on the same machine, it is important that these match. Determining which architecture of Office is installed depends on the version of Office.  For Office 2010,  open an Office program (e.g. Word), then select File > Help, then look for About Microsoft Word  (or other program). Next to the version line will be an indication of whether or not the program is 32 bit.  Note that the clients and servers can work with one another even if the architecture versions do not match.


(Be sure to read the 32/64 bit discussion above)

  • 64-bit Tethys installer v2.3.2
  • 32-bit Tethys installer v2.2
  • 64-bit Tethys installer v2.2
  • 32-bit Tethys installer v2.1
  • 64-bit Tethys installer v2.1

By default, only a small installer program is included.  Once you have selected the components of Tethys you would like installed, they will be downloaded automatically.  Users have occasionally reported problems with the automated downloads.  If this happens to you, please download one of the following zip files which contains everything that is needed.  The zip should be uncompressed, and the Tethys-Installer executable should double clicked to start the installation.   The installer always checks if the needed files are accessible before trying to download them.

  • 64-bit Tethys zipped archive v2.3.2
  • 32 and 64-bit Tethys zipped archive v2.1
  • 32 and 64-bit Tethys zipped archive v2.0

Importing data

Note that to import data, you will need an appropriate open database connectivity (ODBC) connector.  Details can be found in the user manual.  Some common connectors that people might need:

Tethys has been tested with the Microsoft ACE 2010 and MySQL drivers.
