Register Windows Installer

The Microsoft Windows Installer service must be properly installed and registered to install Arcserve RHA. If this service is stopped or damaged, the following error occurs when you install or uninstall certain applications:

Windows Installer Error 1720/1722

There are two ways to avoid this error:

Re-register the current Windows Installer service version
Download the latest Windows Installer service version

To re-register the current version, click Start, Run and type the following commands:

Msiexec/unregister

Msiexec/regserver

To install the latest Windows Installer service version

Go to the Microsoft website and download the latest Windows Installer.
Follow Microsoft's instructions to install the service according to your system requirements.
Restart your computer after installation completes.
Verify the service is running. Click Start, Run and type the following command:
```
services.msc
```
If you are running Vista, type the command in the Start Search box.

The Services screen opens. Look for the Windows Installer service and verify the status is Started. Change the startup type to Automatic, if needed and start the service manually if it is not running.

After Windows Installer is installed and verified, you can install Arcserve RHA.

Initial Arcserve RHA Installation

Installing Arcserve RHA components for the first time is very straightforward. The installation package, which is downloaded from the Arcserve RHA Web site, contains an installation file called Setup.exe. This Setup.exe runs a standard installation wizard that guides you through the installation.

This installation does not require a reboot or application shutdown.
The required level of the Windows Installer (INSTMSI.EXE) is 3.0. Unless otherwise indicated, all supported Operating Systems contain Windows Installer 3.0 as a built-in application.

Standard prompts facilitate the installation. Your only major decision is on which servers to install the different components:

Install Control Service on a computer that is used to monitor and manage all scenarios.
Install Engine on both the Master and Replica servers.
The user who installs Arcserve RHA components must have Local Administrative privileges or be a member of Local Administrators Group.

The default installation directory is:
INSTALLDIR\Program Files\CA\ARCServe RHA\component_names.

During the installation process, you are prompted to enter the service account under which the Arcserve RHA service runs.
If you are running High Availability (HA) scenarios, the account under which the Arcserve RHA service runs may require privileges in addition to those of the local system account. (See the appropriate Arcserve HA Operations Guide for more information.)
A Windows user account running the Arcserve RHA Control Service requires Read-Write permission to the installation directory.
The service logon account for the Arcserve RHA Engine requires Read-Write permission to the installation directory.

Component Installation Workflow

Installing Arcserve RHA basic components consists of several simple steps:

Installing the Control Service - install the Control Service on a stand-alone Microsoft server by using the Setup.exe file, selecting the Arcserve RHA Control Service option, and following the wizard's instructions.
Installing the Manager - open the Arcserve RHA Overview Page. By clicking the Scenario Management link on this page, the system automatically installs the Arcserve RHA Manager on your local computer.
Installing the Engines - open the Manager, and create a new scenario using the Scenario Creation Wizard. During the scenario creation, the system allows you to install the Engine on the Master and Replica hosts that participate in the scenario. You can also install an Engine locally by using the Setup.exe file, or install numerous Engines at once by using the Remote Installer.
