Upgrades are available for our 'Crocodile' simulation and modelling software.
To upgrade to the latest version of Crocodile Physics, Chemistry or Techbnology, you need to buy Crocodilia, our online support service.
Each pack contains an upgrade CD, and also gives a year's access to a website offering any subsequent upgrades, home-use licences for Students and preferential technical support.
The upgrades that you get from Crocodilia are yours to keep, whether or not you buy Crocodilia again the following year. However, the other services are only available while you have a valid support pack.
Upgrades are no longer available from our first software title, Crocodile Clips versions 1, 2 or 3, as this software was discontinued in 1999.
Users of earlier full versions of Crocodile ICT can download a free upgrade to the current version.
In 2004, we decided to give away a limited number of free copies of a first version of Crocodile ICT, which was called version 0. If you were one of the lucky ones to get a free copy of v0, it's yours to keep - it's not a time-limited demo. There's no upgrade to the current from version 0, but we hope that if you liked version 0 you'll consider buying this full version.
We have sent out free upgrades to the current version, on CD-ROM, to all Crocodile Mathematics users.
