Enabling 32-Bit Installations on 64-Bit Windows Computers

If you have a 64-bit Windows computer and you want to protect 32-bit applications, you can configure the installation program to install a 32-bit agent on the computer. This is useful if you need to protect 32-bit versions of the following applications:

  • Documentum
  • Microsoft SQL Server
  • Microsoft Exchange Mailbox
  • IBM Notes Database

Before You Begin

Procedure

Use one of the following two methods to enable a 32-bit installation on a 64-bit Windows computer.

Preferred Method: Using the CommCell Console (Remote Installation)

During a remote installation, on the Enter Additional Install Options page of the installation wizard, select the Install 32-bit instead of default 64-bit packages (Windows X64 only) - This will protect 32-bit applications only check box.

Note: If the computer already has other Commvault software installed (for example, 64-bit agents), you must install the 32-bit agents on a new Commvault instance. To install in a new instance, select the Install new Instance (if required) check box.

For instructions on remote installations, see Installing Commvault Remotely Using the CommCell Console.

Alternate Method: Using the Installation Package (Local Installation)

Before you run the installation package, you must configure a registry key on the 64-bit computer as follows:

  1. Open the Windows Registry Editor, and then go to the following directory:

    HKEY_LOCAL_MACHINE\SOFTWARE\

  2. Right-click SOFTWARE, click New > Key, and then name the new key GalaxyInstallerFlags.
  3. Right-click GalaxyInstallerFlags, and then click New > DWORD (32-bit) Value.
  4. Right-click the new value, click Rename, and then type the following as the new value: bAllow32BitInstallOn64Bit.
  5. Double-click the DWORD key, set the Value Data to 1, and then click OK.
  6. Close the Registry Editor.

After the registry key is created, you can install 32-bit agents by running the installation package. For instructions, see Installing Commvault Locally on Windows Computers Using the Installation Package.
