视觉论坛的各种资源，除了视觉相关的模块有使用外，大部分的都不会使用，所以仅提供资源不能提供技术支持。资源的下载地址一般会同时提供NI官方地址和百度网盘的下载地址。某些工具包NI的地址失效或没有NI的下载地址，那视觉论坛也没有办法，只能尝试使用百度网盘地址下载；如果百度网盘的下载地址失效过期，可联系论坛客服更新。现在NI的下载服务器对我国IP地址不是很友好，有些时候速度很慢或大的资源下载很容易出错，这样会造成安装过程各种类型报错而无法安装。建议在下载完成后，对下载资源做校验和验证（NI一般会提供MD5或SHA256等），与官方或视觉论坛提供的校验和对比，一致就可以安装，如果不一致，则需要重新下载。视觉论坛早期下载的资源，那时候NI没有这么多限制，基本上都是正常下载的资源；后期下载的资源，都与NI的正确校验和对比过，保证是正确的资源才上传到百度网盘，所以百度网盘的资源基本上是正确的。校验和工具下载地址：

Notes
NI-VISA supports the WINNT, GWINNT, WIN64, and GWIN64 frameworks defined by the VXIplug&play Systems Alliance and the IVI Foundation.
The VXIplug&play Systems Alliance developed the concept of a framework to categorize operating systems, programming languages, and I/O software libraries to bring the most useful products to the most end-users. A framework is a logical grouping of the choices that you face when designing a VXI system. You must always choose an operating system and a programming language along with an application development environment (ADE) when building a system. There are trade-offs associated with each of these decisions; many configurations are possible. The VXIplug&play Systems Alliance grouped the most popular operating systems, programming languages, and ADEs into distinct frameworks and defined in-depth specifications to guarantee interoperability of the components within each framework. To claim VXIplug&play compliance, a component must be compliant within a given framework.
Application Software Support
NI-VISA 21.0 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-VISA |
| LabVIEW | 2018, 2019, 2020, 2021 |
| LabVIEW NXG | 5.0, 5.1 |
| LabWindows/CVI | 2017 and later |
| Measurement Studio | 2019 and later |
Microsoft Visual Studio Support for the IVI-Compliant NI-VISA .NET Class Library
If you are using the IVI-compliant NI-VISA .NET Class Library, the .NET 4.6.2 Framework (minimum) is required. You can use the NI-VISA .NET Class Library with the Visual C# or Visual Basic .NET programming languages in any Visual Studio version that can target the .NET 4.0 Framework or later. You can use the NI-VISA .NET Class Library in 32-bit or 64-bit applications.
Microsoft Visual Studio Support for the VisaNS .NET Class Library
Note: The Measurement Studio VisaNS .NET Class Library is being deprecated and superseded by an IVI-compliant NI-VISA .NET Class Library. Refer to the New Features section for more information.
Installation InstructionsInstalling NI-VISA for LabVIEW
You can install all of your LabVIEW products—including NI-VISA—using the LabVIEW 2021 platform media.
To request additional LabVIEW platform media, visit ni.com/r/media.
Note
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.
Before you install NI-VISA 21.0, NI recommends that you uninstall any versions of VISA prior to NI-VISA 2.0.1.
After uninstalling NI-VISA, some DLLs and executables may remain in the NI-VISA directories. To complete the uninstall process, you must restart your machine.
Note: The uninstaller application does not notify you when rebooting is necessary. If you plan to reinstall NI-VISA, you always should reboot the machine after running the uninstaller.
Agilent/HP Controller Support
NI-VISA now works with Agilent/HP GPIB and VXI controller cards. To use this feature, go into MAX, select Tools»NI-VISA»VISA Options, choose the Passports tab, and enable the NiVisaTulip.dll Passport. NI-VISA automatically finds and accesses any GPIB or VXI devices. However, NI-VISA does not configure the Agilent/HP hardware; you still must do that with the Agilent/HP I/O Config utility.
If you have both NI and Agilent/HP controllers in the same system, you must configure the cards at different system addresses, such as GPIB0 and GPIB1. If both vendors try to use the same interface address, NI-VISA reports an error from viFindRsrc or VISA Find Resources.
Creating and Digitally Signing Catalog Files
(Windows 10) If you generate an INF file using the NI-VISA Driver Wizard, you must create and digitally sign a Windows Catalog (.cat) file before you can install the INF file on a Windows 10 machine. For more information about digitally signing a .cat file for Windows 10, visit ni.com/r/infwin8.
For more information about creating and signing catalog files, Microsoft has a Kernel-Mode Code Signing Walkthrough whitepaper that describes the details of this process. The generated catalog file should reference only the INF file.
Product Security and Critical Updates

LabVIEW NXG Support and Considerations
The following sections detail considerations for using LabVIEW NXG with NI-VISA.
LabVIEW NXG Operating Systems and System Requirements
Software support for LabVIEW NXG differs in the following ways:
Installing NI-VISA
NI automates LabVIEW NXG installation using a package manager. Complete the following steps to install NI-VISA for LabVIEW NXG.
Visit ni.com/r/nxgdownload to access the LabVIEW NXG download page.
Click Download LabVIEW NXG.
NI Package Manager installs, then automatically opens a download window.
Select LabVIEW NXG Suite and click the green Install button.
Select LabVIEW NXG 5.1 and NI-VISA.
Complete the installer instructions to download LabVIEW NXG 5.1 and NI-VISA.
Refer to the NI Package Manager Manual for more information about installing, removing, and upgrading NI software using NI Package Manager.
LabVIEW NXG Help
View context help in LabVIEW by pressing <Ctrl-H> and hovering over an object.
Search for items using the search bar in the upper right corner of the LabVIEW window. You can also view context help for the search results.
Additional documentation is available online at ni.com/manuals.
LabVIEW NXG Examples
Launch LabVIEW and click the Learning tab.
LabVIEW lessons are located in the Lessons tab, and LabVIEW Examples are located in the Examples tab. Follow the instructions in the lessons and examples.
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.
