Flexible Deployment and Licensing options

ENERCALC offers 2 deployment options for Structural Engineering Library: Installed on your computer and cloud-based usage.

Cloud-based Usage: No license management / activation is required when using our software in the cloud. We call this service ENERCALC SE Cloud.

Installed on your computer(s): When our software is installed on your computer(s), you have 2 activation (license management) options: Internet-based or Network License Manager

Activation / License Management options:

  • Internet Activation / License Management – 99.98% of our users take advantage of our Internet Activation system. It allows you to share your maximum seat count easily between computers. The software can be installed on any computer and "Internet Activation" takes only seconds.

    Once activated on your computer, there is no need to "reactivate" every time you use it. We have users who have not changed their activations in years.

    It can even be automatic for total flexibility, allowing any user to simply launch and end their session without knowing an activation is taking place. Our system is the ideal answer to flexible license management... leaving USB keys as a relic of the past. Only a simple Internet connection is needed (HTTP/HTTPS).

    Installation & Activation instructions for Internet activation users

  • Network License Manager - In rare instances where Internet Activation cannot be used (such as where strict Internet communication policies prohibit its use), we also offer a locally installed usage manager called the Network License Manager (NLM).

    The NLM can be installed on your own server or dedicated computer, and 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 seat limit. Use of the NLM requires a two seat minimum.

We don't use machine specific licensing or inconvenient hardware devices like "dongles" or USB keys.
