Electronic Program Updates

As a user of our software you are probably entitled to update it to the latest version at any time, the only proviso being that the software is covered by current software maintenance. To have current maintenance, the software should be within it’s original cover period from sale (usually a year), under maintenance contract or under a rental agreement.

  • We are continually refining and developing our software. Updates can be done on as much as a daily basis. We don't 'hold back' software for specific release dates - our software is released as and when it has been written and tested.
