Planning a Client Installation on Windows Computers

Use the following information to prepare for the installation of agents or other Commvault software on Windows computers.

1. Review Requirements

Review Commvault package requirements. For more information, see Commvault Packages Available for Windows Computers.

2. Download the Software

Choose one of the following methods to download the software:

3. Collect Cluster Environment Details

If you plan to install a Commvault package on a cluster environment, review the following information to prepare for the installation.


To determine whether the package can be installed on a cluster environment, see Cluster Configuration - Support.

Review the Operating System

Commvault installations are not supported on Windows 2003 Server (and below) cluster environments.

Review Network TCP Port Requirements

The physical nodes that host the cluster server must have the same port numbers configured. For example, if you have a cluster server VS1 and three physical computers configured to host VS1, then the three physical computers must have the same network TCP port numbers configured on the network interface used by VS1.

Select Physical Nodes to Install the Software

Select the physical nodes (active and passive) on which you want to install the package. In the event of a failure, the active node can fail over to one of the passive nodes.

Collect Domain Administrator Account Details

If you plan to use the CommCell Console to install the software remotely on the physical nodes, the installation program requires the user name and password of the Domain Administrator account. The Domain Administrator account must have full domain administrative rights on the active and all passive nodes where you plan to perform the installation.

Windows fresh push installs with credentials that have the "Deny log on locally" and "Deny log on through Remote Desktop Services" restrictions are supported. But those accounts still need access to the admin share and remote registry.

Remote push installation is not supported when multi-factor authentication is enabled on the client.

4. Determine the Configurations that Meet Your Requirements

Every environment has different requirements. Consider the following additional configurations and information prior to completing your installation planning.

Install Restore-Only Agents

If you plan to use the client computer only as a destination for restoring backup data, you can install the agent in restore-only mode. Before the installation, review the considerations described in Installation of Restore Only Agents.

Install 32-bit Agents on 64-bit Computers

If you need to protect 32-bit application data on Windows 64-bit computers, you can install agents in 32-bit mode. The preferred method for installing 32-bit agents on 64-bit computers is to install the agents by using the CommCell Console.

For more information, see Enabling 32-Bit Installations on 64-Bit Windows Computers.

Install Commvault in a Different Language

This configuration is only applicable if you plan to use the installation package to install the software listed in Language Support.

If you want to install the software in a different language, you can configure the installation program to list the supported language options. For more information, see Changing the Display Language of the Commvault Software on Windows Computers.

Change the Branding of the Installation Package

If you want the installation wizard to display your company name and logo, and to adjust other branding settings, see Changing the Branding Settings of a Windows Installation Package.

Install Commvault in a New Instance

If Commvault is already installed on the computer, but your environment requires a separate instance of the software, you can install Commvault in a new instance. For more information, see Multi-Instance Installations.

Install Commvault on Computers Sharing the Same Host Name

If you want to use the same host name and CVD port number on multiple computers during the installation, you can configure the CommServe computer to allow clients that have the same host name and CVD port.

For more information, see Allowing a Duplicate Hostname and CVD Port During Client Installation.

Install Commvault Using a Temporary Client Certificate

If you want to install Commvault on a client using a temporary client certificate, see Installing a Client with a Temporary Client Certificate.

Review Database Service Restart Requirement for Database Agents

If you plan to install database agents, the database services might need a restart to complete the agent installation. The installation wizard provides the required options to restart database services during the installation.

To determine whether your agent requires a database restart, see Database Service Restart Requirements when Deploying Windows Agents.
