This type of installation is designated for clients with ESS/EAV version 4.2 and later. Beginning with version 4.2, a new upgrade mechanism was implemented that allows ERA to initiate the upgrade process on the client side without the need of the einstaller.exe agent. This mechanism works in a manner similar to the program component update, - or PCU, which upgrades clients to a newer version of the program. For version 4.2 and later ESS/EAV clients, we strongly recommend this type of upgrade.


NOTE: If a custom configuration file has been defined for the installation package it will be ignored during the upgrade.
