Difficulty with Internet Activation

I am having trouble with Internet Activation of my Flex License

 

These issues almost always come down to a communication issue between your computer and the Internet Activation system.  These issues generally fall into one of four categories:

 

Anti-virus software is blocking proper communication.

A firewall is blocking proper communication.

Your system may be configured to use a Proxy Server for Internet access.

Ad blocking software and “firewall boosters” have also been known cause communication issues.

 

We would recommend that you check into these items:

 

Check your firewall and anti-virus software to verify that www.enercalc.com and enercalc.net (not www.enercalc.net) are permitted/trusted.  Be aware that builds 10.19 and later use HTTPS to activate, which requires using the domain name (enercalc.net) rather than the IP address.  Allow ports 80 and 443.

Check to be sure that you are running the latest available build of the program by updating with the following link:  https://install.enercalc.com/EC20_update/EC20_UPDATE.EXE.  

 

If you check all of these things and still can’t activate, please let us know.

 

Note:  The Internet Activation server continually runs self-diagnostics, and restarts itself within four minutes if an issue is detected.  So any issue with the server will commonly resolve itself within a few minutes, and the easiest fix is to just try Internet Activating again.
