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：

Overview
NI-845x software for Windows is required to use the NI USB-8451 and NI USB-8452 I2C and SPI interfaces.
The NI-845x Software and Hardware Installation Guide included with the NI-845x CD includes instructions for installing National Instruments hardware and software.
The primary document for NI 845x products is the NI-845x Hardware and Software Manual. This manual includes an introduction to I2C and SPI buses, specifications for hardware, information about how to get started with application development, and a complete reference for all NI-845x functions.
To view the manual, select National Instruments»NI-845x»NI-845x Documentation»NI-845x Hardware and Software Manual.pdf from the Windows Start menu or NI Launcher.
Links to the NI-845x Hardware and Software Manual are in the online help for each NI-845x function within the National Instruments LabVIEW and LabWindows™/CVI™ development environments.
Supported Operating Systems
NI-845x 20.0 supports the following operating systems:
Windows 10/8.11/7 SP12
Windows Embedded Standard 7 SP12
Windows Server 2012 R21 (64-bit)
Windows Server 2008 R2 SP12 (64-bit, not supported on Server Core Role)
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.
The NI-845x installer does not support Windows 2000/NT/Me/98/95 or the Windows Server non-R2 editions.
Note In 2016, NI-845x dropped support for Windows Vista, Windows XP, Windows Server 2003, and installations of Windows 7 without any service packs. This software release will not install or run on an unsupported OS. You cannot deploy or distribute applications that use this release to an unsupported OS. Additionally, after installing this release, 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 KB 79UC78LS, Why Does my LabVIEW, LabWindows/CVI, Measurement Studio, or TestStand Built Installer Fail on Windows XP/Vista and 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/info and enter the Info Code PAESupport.
NI-845x Drops Support for Windows 7 (32- and 64-Bit), Windows Server 2008 R2, and All 32-Bit Windows Operating Systems in 2021

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 4.0, 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 4.0 separately before you install NI software.
For more information about automating the installation of NI products, refer to the following KnowledgeBase articles:
For more information about silent installations of individual NI products, refer to KB 4CJDP38M, Automating the Installation of a Single Installer.
For more information about silent installations of NI products in a suite, such as NI Developer Suite, refer to KB 4GGGDQH0, How Do I Automate the Installation of a Suited Installer?.
To determine what version of NI Installers your product contains, refer to KB 4CJDR18M, How Can I Determine the Type and Version of My NI Installer?.
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.
