|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.
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.
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.
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.
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.
Use the LabVIEW Platform media to install modules and toolkits supported by LabVIEW 2020 (32-bit) and LabVIEW 2020 (64-bit). When run on Windows (64-bit), LabVIEW (64-bit) provides access to more memory than a 32-bit operating system or a 32-bit application can provide. LabVIEW (64-bit) is available in English only.
Refer to the NI website for information about drivers compatible with LabVIEW 2020 (64-bit). For GPIB devices, you must use at least NI-488.2 2.6 for Windows. Refer to the specific hardware documentation for more information about compatibility with LabVIEW (64-bit).
LabVIEW 2020 (64-bit) supports a limited number of modules and toolkits. The following table compares the modules and toolkits supported by LabVIEW (32-bit) and LabVIEW (64-bit).

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.
Microsoft Windows 10 is the latest version of the Windows operating system and features significant changes compared to previous versions.
