Flexible Licensing

ENERCALC offers multiple software licensing options. These include single-computer, local network, Internet Activation, Network Licenses (for systems not connected to the internet), academic / educational, plan check, and cloud-based.

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. See "Internet License Activation" below.

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 click the [Internet Activate] button and the license is activated on your computer. When you want to use another computer, click the [Internet Deactivate] button. 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 inconvenient hardware devices like "dongles" or USB keys. Our Internet Activation needs only a momentary Internet connection when you activate the software (using http over port 80).
