Installation and Licensing Configurations

There are three available options for licensing the Structural Engineering Library:

  • Flex License : Uses Internet Activation to request and receive permission to run. Software can be installed on as many computers as desired.
  • Cloud Usage : Allows the user to log in to a cloud hosted session of the software using any HTML5 compliant browser, and store projects on ENERCALC’s cloud-hosted storage server.
  • Network License : Uses ENERCALC's Network License Manager (NLM) installed on a computer in your office. The NLM will grant permission to run on a number of computers up to the number of available seats.  The SEL can be installed on as many computers as desired.

For Flex License installations, the software must be activated on a computer in order to be used.  The activation is granted over the Internet on a seat by seat basis.  This means that you have the flexibility to install the software on any computer where you might like to use it. You can then use the Internet Activate/Deactivate feature to move the activation to any computer where the Structural Engineering Library is installed.

For example, if you have activated the software on your work computer and will be working at home for the weekend, you can click “Internet Deactivate” on your work computer and then click "Internet Activate" on your other computer. Only a brief moment of Internet connectivity is needed for activation/ deactivation.  (If you forgot to deactivate the office computer before leaving there is no problem....we have a method of handling that common occurrence).

For Network License installations you will install our Network License Manager (NLM) on one of your computers. It will run as a "service" and the computer where it is installed must be visible over your network to the computer(s) where the Structural Engineering Library (SEL) is installed. When the SEL is launched it contacts the NLM and receives permission to run as a "Licensed & Activated" installation.

For Cloud Usage you subscribe to the Cloud service and then log in using your web browser to access your Projects and to run the software. This is a monthly subscription with a very low initial start-up fee.
