Elicencer fails to enter activation code

mac os 1.2.3, eLC Version

all licence downloads to USB e-licencer are failing

starting licence download runs for 10-20 minutes then fails

eLicenser Control - Error

Application ‘LCC2’ has caused the following error:

An unknown interapplication communication error occured. In case the problem persists, please close all applications and restart your computer.

click ok

e-licencer does not recover well from this error

it goes to reading e-licences and stays there for a long time before showing licences


What macOS version do you have, please? Are you sure, there is no firewall or something other blocking the communication?

Big Sur 11.2.3
I turned off the firewall and its working now
many thanks Martin
