Error Code 4 received during installation or activation

Error Code 4 is displayed during the installation or activation.

As a part of the industry wide initiative to migrate from SHA-1 to SHA-2 SSL certificates, Alt-N Technologies will take proactive measures to further secure its software licensing system by replacing end-point and intermediate server certificates with SHA-2 SSL certificates.

Effective date of the new SHA-2 SSL certificate on Alt-N servers:  January 20, 2015

Non-current Windows Server 2003 and Windows XP operating systems could experience license activation or validation issues when attempting to communicate with Alt-N software licensing system(s).

NOTE:  Microsoft Server 2013 operating systems that are receiving regular scheduled (or manual) Microsoft updates should have already received the KB2868626 update and will likely require no further attention.  It is recommended, however, that administrators verify that the update has been applied. 

There are four potential reasons an Error Code 4 would occur during an installation or activation;

  • Port 443 unavailable
  • SSL Filtering
  • Installation is behind a proxy
  • Microsoft Security Update 2868626 has not been applied
