Automation Builder 1.2 License File Location
As far as I know, if the software was activated by entering the license key number in the license entry window, during installation,then the activation code gets registered against the MAC ID of the PC's NIC in ABB's license server (via. an active internet connection). There may not be an offline license file as such, but a registry entry.
In case you are using a dongle, then a license file will be stored in it.
The activation code is normally provided on a laminated sheet of paper for reference, in case the software has to be re-installed due to corruption in AB or PC OS.
