The ESMC 7.1/7.2 Server component only supports 64-bit operating systems. If you are running ERA 6.5 or ESMC 7.0 on a 32-bit machine, you need to migrate to a 64-bit machine before the upgrade to ESMC 7.2
Before upgrading to ESMC 7.2, make sure that all ESMC 7 installation prerequisites are met.
To manually upgrade ESET Remote Administrator 6.5 and later to ESET Security Management Center 7.2, follow the instructions below:
Read the End-User License Agreement, click I accept the terms in the License Agreement and then click Next.
Continue with the upgrade of ERA Proxy to Apache HTTP Proxy and ERA Agents to ESET Management Agents on the client computers.
