HI Michalj,
my issue is EEA activate key has blocked in ESET File Secuirty. When the ESET file security and ESET Remote Administrator service on my ESET Server running, all EEA on client machine can not activate the key license but when i disable the EFS and ERA service on my EET Server, all EEA on client machine can activate the key lices, thus i think the key license has blocked with EFS and ERA.
that is my real issue?
