Flex License. Allows you to install the software on multiple computers. Using our simple Internet Activation system you can share your license between easily between those computers. An Internet connection is only needed at the moment of activation and your software will stay activated. Simultaneous usage is dependent on the number of seats purchased.

Network Licenses include the ENERCALC Network License Manager (NLM) which you install on your own server or dedicated computer, which can then be accessed by authorized users over your LAN by IP address. The NLM grants users permission to run the software simultaneously, up to your purchased license limit. Network licenses require a two seat minimum.

Internet License Activation is central to the flexible use of your software at any location you choose. You simply press [Internet Activate] and the license is activated on your computer. When you want to use another computer just [Internet Deactivate].....if it is still activated on another computer that computer will be deactivated and your active license moved to the current computer. This means you can have the Structural Engineering Library installed on any computer you choose and just activate whichever one you desire. Our system makes sure you have the proper number of active licenses.

We don't use machine specific licensing or USB keys which are considered inconvenient. Our Internet Activation needs only a momentary Internet connection when you activate the software (using http over port 80).
