This article relates to using a local license; the licensing scheme used in PROKON ver. 2.6 and earlier. PROKON ver. 3.0 introduces a new licensing option – License Manager – that performs automatic license activation. With License Manager, there is no need for manual activation or deactivation. You can install PROKON anywhere and simply log in to use your license. For more information, please see the PROKON Web Help.
When chosing to activate (or deactivate) PROKON using the Direct Internet Activation (or Deactivation) method, nothing happens.
This issue was resolved with the release of PROKON Calcpad version 18.104.22.168 on 12 September 2011. Please update your software if you are using an older version. The executable license key (e.g. Key_xxxxx.exe) is no longer required; you can safely delete it.
Some anti-virus packages consider the executable key that performs the Internet activation and deactivation to be potentially harmful. The executable key is often moved to the anti-virus quarantine or blocked from running. To the user is would simply seem as if nothing is happening when selecting "Direct Internet Activation" (or Deactivation).
At the root of the problem lies the fact that PROKON executable license keys are not digitally signed; the rest of the PROKON modules are signed. (Digital signatures build trust by confirming the software publisher.) This is so because each license key is unique and compiled specially for each user. The lack of a digital signature plus the ability of an executable license key to make an Internet connection (to communicate with the PROKON license server) may seem suspicious to anti-virus software, resulting in the mentioned blocking.
The analysis by the anti-virus software are "false positives", i.e. incorrect identification of a threats when there are none. PROKON software is free from virusses. We have been reported the issue to numerous anti-virus vendors, but to no effect.
