ERAS works as a service, and therefore requires a Microsoft Windows NT-based operating system. Although the Microsoft Windows Server Edition is not necessary for ERAS to work, we recommend installing ERAS on server-based operating systems for smooth operation. A computer with ERAS installed on it should always be online and accessible via computer network by:

Clients (usually workstations)

PC with ERA Console

Other instances of ERAS (if replicated)

NOTE: ESET Remote Administrator 5 supports installation over previous versions including data migration.
