WLAN Toolkit Drops Support for Windows 7 and Windows Server 2008 R2 in 2021
The WLAN Toolkit gives you direct and fine control over the generation and analysis of IEEE 802.11a/b/g/n/ac and ax signals, as well as 802.11j/p/ah/af waveforms, with industry-leading speed and accuracy. It empowers you to characterize, validate, and test a variety of WLAN connectivity products, such as RF front end components, wireless modules, and user devices.
WLAN Toolkit 19.1 supports the following 64-bit 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 for more information about how to install this security update.
WLAN Toolkit 19.1 supports the following application software versions, including service packs. If you are not using NI application software, refer to Microsoft Visual Studio Support.

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 the following KnowledgeBase articles:
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.
When you install National Instruments 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.
WLAN Toolkit will drop support for Windows 7 and Windows Server 2008 R2 starting from 2021. Versions of this product that ship after May 1, 2021, will not install or run on these operating systems. For detailed information about NI operating system support, visit ni.com/r/win32bitsupport.
