System Requirements for Windows

Updated

Verify that your environment meets the system requirements for the Windows file system.

Operating System

Important: Use the most recent version of the operating system that is listed. The Commvault software fully supports the most recent version of an operating system, until the vendor ends support. More recent versions of the Commvault software might not install on operating systems that are not supported by the vendor anymore. For information about the support lifecycle of an operating system, contact the vendor.

Software That Is Automatically Installed

.NET Framework

On most versions of Windows, the .NET Framework 4.6.2 is automatically installed.

On Windows 2008 and Windows Vista, the .NET Framework 4.0 is automatically installed.

Visual C++ Redistributable 2017

Starting in Service Pack 17, the Microsoft Visual C++ Redistributable 2017 (vcredist2017.exe) is automatically installed.

If a computer does not have the most recent Windows updates, then the installation of Universal C Runtime, as part of the installation of Microsoft Visual C++ Redistributable 2017, fails. To prevent the installation failure, install the following Windows updates:

  • KB2919355

  • KB2939087

  • KB2975061

  • KB2999226

Updates are not required on the most recent Windows operating system versions, such as Microsoft Windows 10 and Microsoft Windows Server 2016, because the Universal C Runtime is already installed on those versions.

When possible, Commvault provides information on any known issues related to these minor releases or feature releases.
