This file contains important information about NI-DMM, including installation instructions, new features, bugs fixes, and known issues.
If you plan to use LabVIEW NXG, refer to LabVIEW NXG Support and Considerations.
NI-DMM is an NI instrument driver that communicates with all NI programmable digital multimeters (DMMs). NI-DMM is an interchangeable virtual instrument (IVI)–compliant instrument driver, and it features a set of operations and properties that exercise the functionality of the DMM and includes an interactive soft front panel and examples.
NI-DMM 20.0 has the following requirements:
Refer to the LabVIEW Readme for additional system requirements and supported operating systems for LabVIEW.
NI-DMM 20.0 supports the following operating systems:
1 NI software installs VC2015 Runtime and .NET 4.6.2. Windows 8.1 and Windows Server 2012 R2 require Microsoft updates to support these items. Refer to Microsoft KB2919442 and KB2919355 for more information about how to install these updates.
2 NI software is signed with a SHA-256 certificate. Windows 7 SP1, Windows Embedded Standard 7 SP1, and Windows Server 2008 R2 SP1 require Microsoft updates to support SHA-256. Refer to Microsoft KB3033929 and KB3125574 for more information about how to install these updates.
Note In 2016 NI-DMM dropped support for Windows Vista, Windows XP, Windows Server 2003, and installations of Windows 7 without any service packs. NI-DMM 20.0 will not install or run on an unsupported OS. You cannot deploy or distribute applications that use NI-DMM 20.0 to an unsupported OS. Additionally, after installing NI-DMM 20.0, you cannot use any installers built on this computer with any version of LabVIEW, LabWindows™/CVI™, NI TestStand™, or Measurement Studio on an unsupported OS.
For more information about the changes to our OS support for 2016, refer to Why Does My NI ADE Installer Fail on Windows XP/Vista and Windows Server 2003?.
Note Support for Windows 32-bit operating systems may require disabling physical address extension (PAE). To learn how this might affect your system and what actions you might need to take, visit ni.com/r/PAESupport.
Note Refer to NI-DMM Drops Support for Windows 7 (32- and 64-Bit), Windows Server 2008 R2, and All 32-Bit Windows Operating Systems in 2021 for information about future OS support.
NI-DMM 20.0 supports the following application software versions, including service packs. If you are not using NI application software, refer to Microsoft Visual Studio Support.
|Application Software||Versions Supported by NI-DMM|
|LabVIEW||2017, 2018, 2019, 2020|
|LabVIEW Real-Time Module||2017, 2018, 2019, 2020|

If you are using the NI-DMM .NET Class Library, the .NET Framework 4.0 (minimum) is required. The NI-DMM .NET Class Library can be used with the Visual C# or Visual Basic .NET programming languages in any Visual Studio version that can target the .NET Framework 4.0 or the .NET Framework 4.5.
To use the .NET API, you must select the .NET Framework 4.0 Languages Support or the .NET Framework 4.5 Languages Support packages in the NI-DMM installer to install the .NET class libraries in addition to the NI device driver. For information about versions of the .NET Framework and the drivers each supports, as well as the download location of the installer files, refer to National Instruments .NET Driver Support.
NI installs NI-DMM using NI Package Manager. If you do not already have NI software installed, NI-DMM installs NI Package Manager to handle the installation of your NI software. Visit ni.com/r/NIPMDownload to download NI Package Manager. Refer to the NI Package Manager Manual for more information about installing, removing, and upgrading NI software using NI Package Manager.
The following list details the hardware models supported in NI-DMM 20.0.
