Taverna 2.2 for Windows

If you have administrator rights on your machine, you can download the Windows installer. A wizard will guide you through the installation to C:\Program Files and will add Taverna to the Start menu. If you do not have a recent Java, the wizard will also help you install the newest Java from Sun.
If you do not have administrator rights, you can download the Windows archive instead – this is simply a self-extracting 7zip archive. You can place the extracted folder wherever you like. Start Taverna by double clicking on taverna-x.y.z.exe.
Note: It has been reported to us that sometimes on Windows, if you are downloading the Taverna archive (not the Windows installer!) on a wireless network that might drop the connection unexpectedly, you may get an incomplete download. The installers should detect incomplete archives and report a failure, but to be certain you should also verify the SHA1 or MD5 checksum and download again if necessary.
If you need to make any changes to the Java parameters, such as the amount of memory allocated (by default the minimum of 500 MB or 50% of free memory), or are a developer interested in debug messages, use taverna-debug.bat instead of the executable.
Taverna 2.2 for Mac OS X
|
|
Download the OS X disk image. After opening the disk image, a Finder window should appear. You can then drag the Taverna application into your Application folder, or wherever you prefer to keep the application. Double-click on the installed application (not the one in the disk image) to start Taverna.
Taverna 2.2 for Linux
|
|
Download the Linux archive and unpack it using tar zxfv taverna-workbench-2.2.0.tar.gz or by double-clicking it in your desktop environment. Make sure that you have both SUN Java 1.5 JRE or higher and Graphviz installed.
Place the extracted folder wherever you like, start a terminal, and run ./taverna.sh to start Taverna. If you have any problems, double-check that you are using the official Sun java by running java -version.
