Ecotect v5.6 and Earlier

License services for Ecotect v5.6 and earlier are still maintained. In fact, users of Ecotect v5.6 or earlier can now manage their own licenses manually.

You will need to know at least the email address and/or password of your licence account, the Proof of Purchase (POP) number of your Ecotect v5 licences or some combination of these in order to access your licenses online. This is the same information that was required for the original software activation process.

Important Information

Network License Issues

14 March 2011

Some reported problems with old network licenses can be resolved by updating your local license server to Network Licence Manager v2 (2008). This is solely for legacy Ecotect 5.X licenses, not the Autodesk Flex licensing that started with Ecotect 2009, so it will work fine with all your existing SQU1 licenses.

License Server Changes

15 February 2011

The Ecotect legacy license server has moved. It is still but the IP address it resolves to is now You may need to update your firewall rules if your company restricts external internet access.
