Is there a trial period or an unregistered version of the software available? If so how long is the trial period?
The software producers offer a trial version for this tool. The trial version it's available for 30 days but the functionality of the tool is not as good as the full version of it. To find out more about the trial version and to get a download link you can visit the following link: http://www.wolfram.com/mathematica/trial/
