When a registered version of GeoTools or CADPower loads, it is common to see a startup message which looks like:
Reading F:\projects\1111_cadpower\CADPowerUser14_EN_AC.rgs...
Successfully read CADPower registration information...
CADPower Version 14.13 [English], Registered to ACROPOLIS,
GUID File could not be obtained. Maybe there is no internet connection
CADPower command shortcut macros defined.
Today, one of our users asked for clarification on what exactly this message about GUID files meant. This post explains it all. GeoTools/CADPower licensing mechanism can (optionally) use a GUID file placed on the licensing server (on our web-site) to authenticate your licenses.
If your internet connection is ON during GeoTools/CADPower startup, the system will search for the GUID file and if present, will authenticate your license. If the internet connection does not exists,, the message "GUID file could not be found" is shown, and this is only a diagnostic message indicating that the licensing mechanism could not locate a GUID file, so no action is taken as a result.
By default, the GUID file is not placed on our server, so the online authentication is OFF and does not happen.
You can safely ignore this message.
However, if you do not like to see the message, we will be happy to re-issue your license with even the startup check for GUID completely removed.
You can check if your licenses are attempting a GUID check on the server by clicking on More Options -> License info or type GT_DISPLAYLICENSEINFO / CP_DISPLAYLICENSEINFO on the command line (see diaog below).
Why is the GUID check & authentication useful?
We use this as a automatic license deployment mechanism on large multi-user environments. If there is a matching GUID file on the server, it will help update user-licenses automatically. This reduces support work during deployment of very large number of multi-user licenses or to track usage on environments where frequent enabling and disabling of license keys happen.
