System Requirements

LabVIEW 2020 has the following requirements:

Windows	Run-Time Engine	Development Environment
Processor1	Pentium 4M/Celeron 866 MHz (or equivalent) or later (32-bit) Pentium 4 G1 (or equivalent) or later (64-bit)	Pentium 4M (or equivalent) or later (32-bit) Pentium 4 G1 (or equivalent) or later (64-bit)
RAM	256 MB	1 GB
Screen Resolution	1024 x 768 pixels	1024 x 768 pixels
Operating System	Windows 10 (version 1909)/8.1 Update 12/7 SP13 Windows Server 2016 Windows Server 2012 R22 Windows Server 2008 R2 SP13	Windows 10 (version 1909)/8.1 Update 12/7 SP13 Windows Server 2016 Windows Server 2012 R22 Windows Server 2008 R2 SP13
Disk Space	620 MB	5 GB (includes default drivers)
Color Palette	N/A	LabVIEW and the LabVIEW Help contain 16-bit color graphics. LabVIEW requires a minimum color palette setting of 16-bit color.
Temporary Files Directory	N/A	LabVIEW uses a directory for storing temporary files. NI recommends that you have several megabytes of disk space available for this temporary directory.
Adobe Reader	N/A	You must have Adobe Reader 7.0 or later installed to search PDF versions of all LabVIEW manuals.
1 LabVIEW and LabVIEW Run-Time Engine require processors of the Pentium 4M/G1 generation or later, which are capable of executing SSE2 instructions. 2 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. 3 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 for more information about how to install this security update. Note You cannot access LabVIEW using a Guest account on Windows. In 2016 LabVIEW dropped support for Windows Vista, Windows XP, Windows Server 2003, and installations of Windows 7 without any service packs. LabVIEW 2020 will not install or run on an unsupported OS. You cannot deploy or distribute applications that use LabVIEW 2020 to an unsupported OS. Additionally, after installing LabVIEW 2020, 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, visit ni.com/r/OSSupport2016. 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. Refer to LabVIEW 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.

Installation Instructions

NI installs software using NI Package Manager. If you do not already have NI software installed, LabVIEW 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.

Notes

• If Windows Update is enabled, the installation process might hang if Windows Update interferes with the installation of Microsoft Visual C++ 2015 Run-Time. Visit ni.com/r/exjq43 for more information and steps to resolve this issue.
• If you purchased this product with an NI Software Suite or NI Product Bundle, use the installation media that shipped with your purchase to install this product.
• When prompted, enter the serial number to activate LabVIEW. Your serial number can be found at ni.com/myproducts. If you are managing your license with a volume license server, you should receive your volume license file by email.
  

If you install software using the LabVIEW Platform media, insert the LabVIEW Platform media and follow the onscreen instructions to install LabVIEW, modules, toolkits, and drivers. When prompted, log in to your NI User Account to activate your NI products. If you are managing your license with a volume license server, you should receive your volume license file by email.

Are you upgrading from a previous version of LabVIEW?

Refer to the LabVIEW Upgrade Notes for information about protecting existing VIs and projects before installing a new version of LabVIEW, as well as upgrade and compatibility issues and a complete list of new features in LabVIEW 2020.

Changes to selection rules for named Bundle and Unbundle nodes inside malleable VIs

The rules for how LabVIEW selects cluster elements when you use a Bundle By Name function, Unbundle By Name function, or Unbundle / Bundle Elements Border Node have improved. The improvements may cause existing code to behave differently than you expect when you use these nodes inside a malleable VI. Visit ni.com/r/eakjbu for more information about how these changes impact existing code.

Patch Details

Visit LabVIEW 2020 Patch Details for detailed information about all patches available for LabVIEW 2020 and issues fixed in each patch.

Accessing the Help

Refer to the LabVIEW Help, accessible by selecting Help»LabVIEW Help from LabVIEW, for information about LabVIEW 2020.

Finding Examples

Select Help»Find Examples from LabVIEW to launch the NI Example Finder. You can modify an example VI to fit an application, or you can copy and paste from one or more examples into a VI that you create.

Automating the Installation of NI Products

You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes.

If the NI product you are installing uses Microsoft .NET 4.6.2, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.6.2 separately before you install NI software.

For more information about automating the installation of NI products, refer to Automating an Installer in the NI Package Manager manual.

Using NI Software with Microsoft Windows 10

Microsoft Windows 10 is the latest version of the Windows operating system and features significant changes compared to previous versions. Windows 10 introduces several new capabilities and also combines features from both Windows 7 and Windows 8. For more information about NI support for Windows 10, visit ni.com/windows10.

Using NI Software with Microsoft Windows 8.1

When you install NI software on Microsoft Windows 8.1, you will notice a few additional tiles in the Apps view, including shortcuts to NI application software products such as NI LabVIEW, Measurement & Automation Explorer (NI MAX), and NI Launcher. For more information about NI support for Windows 8.1, visit ni.com/windows8.
