Hi @OBR CTM,
I think we need to up the logging to debug level and then acquire some logs for me so I can see if the Agent is communicating the 'Activation' task and if it is erroring on the EFDE Client with higher debugging.
To do this access the following path in the Registry:
HKEY_LOCAL_MACHINE\SOFTWARE\ESET\ESET Full Disk Encryption\CurrentVersion\AIS\Logs\Loggers
Change 'License' from "info" to "debug"
Re-attempt the 'Activation' task and leave it time to process (EP Console should update if you it is sent or failed) and then acquire these logs if you have issues: https://www.eset.com/int/support/log-collector/
Thank you.
