How to Install the Arcserve RHA Engine

This section describes how to install the Arcserve RHA Engine.

The following are three ways to install the Arcserve RHA Engine:

Using the Setup.exe file - install the Engine on one host at a time. This installation method automatically detects an Engine from a previous version, and enables you to remove it during the installation of the new Engine. The installation steps are similar to the Control Service installation steps, as described on Installing the Arcserve RHA Control Service.
Using the Scenario Creation Wizard - remotely install the Engine on the Master and Replica hosts, during the creation of a new scenario.
Using the Remote Installer - remotely install the Engine on one or more hosts at once, by using the Remote Installer wizard.

Before you install the RHA engine on a Windows 2008 R2 Server Core, register the ieproxy.dll and install the Visual C++ 2005 redistributable package.

Navigate to the %programfiles%\Internet Explorer folder on a Windows Server 2008 R2 (non Server Core installation).
Locate the ieproxy.dll file and copy it to the following location on the Server Core:
```
%systemRoot%\system32
```
To register, enter the following command at the command prompt:
```
regsvr32 %systemRoot%\system32\ieproxy.dll
```
Install the Microsoft Visual C++ 2005 Redistributable Package (x64). Download the Redistributable Package from www.microsoft.com.
