Windows系统下（Linux和MAC系统下请自行了解清楚）NI的各种软件、模块、工具包、驱动程序，使用NI许可证管理器来激活的，绝大部分的都可以使用NI Lincense Activator来激活，以下链接可下载：

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：

Documentation

The NI-845x Software and Hardware Installation Guide included with the NI-845x CD includes instructions for installing National Instruments hardware and software.

The NI-845x Hardware and Software Manual is the primary document for NI 845x products. 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.

The NI-845x Hardware and Software Manual is in Adobe Acrobat Portable Document Format (PDF). You can download the Acrobat Reader for free at: www.adobe.com.

Open the manual from Start»All Programs»National Instruments»NI-845x.

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 PlatformsSupported Operating Systems

You can install and run this version of the NI-845x software on the following operating systems:

Windows 7 (32-bit and 64-bit)
Windows Vista Business edition, Service Pack (SP) 1 or greater (32-bit and 64-bit)
Windows XP (32-bit) SP3 or greater
Windows Server 2003 R2, SP2 or greater (32-bit)
Windows Server 2008 R2, SP1 or greater (64-bit, not supported on Server Core Role)

The NI-845x installer does not support Windows NT/Me/2000/98/95 or the Windows Server non-R2 editions.

Note: Support for Windows Server 2003 R2 may require disabling physical address extensions (PAE). To learn how this may affect your use of Windows Server 2003 and what actions you may need to take, visit ni.com/info and enter the info code PAESupport.

Caution If you plan to perform an upgrade of your system from a prior version of Microsoft Windows to Microsoft Windows Vista, you are required to uninstall all National Instruments software prior to performing the upgrade. After the upgrade has been completed, you can reinstall your National Instruments software.

Supported Hardware

This version of the NI-845x software supports the following National Instruments hardware products:

National Instruments USB-8451 I2C/SPI Interface
National Instruments USB-8451 (OEM) I2C/SPI Interface
National Instruments USB-8452 I2C/SPI Interface
National Instruments USB-8452 (OEM) I2C/SPI Interface

The NI-845x software supports only National Instruments I2C and SPI hardware products. For information about software for I2C and SPI products from other vendors, refer to the documentation you received with those products.

Supported Development Environments

This version of the NI-845x software supports the following development environments:

LabVIEW 2009 (32-bit and 64-bit), LabVIEW 2010 (32-bit and 64-bit), LabVIEW 2011 (32-bit and 64-bit) and LabVIEW 2012 (32-bit and 64-bit)
LabWindows/CVI 8.0 and higher
Microsoft Visual C/C++ 6.0 (or newer)

Installing NI-845x

Before installing the NI-845x software, log on as Administrator or as a user with Administrator privileges. The NI-845x software setup program must have Administrator privileges because the program modifies the configuration registry of your system. Complete the following steps to install the NI-845x software.

Insert the NI-845x installation media into your CD-ROM or DVD-ROM drive. The installer launches if your optical drive plays data disks automatically. If the installer does not launch automatically, navigate to the media using Windows Explorer and launch the autorun.exe file from your NI-845x installation media.
The installation wizard guides you through the necessary steps to install the NI-845x software. You can go back and change values where appropriate by clicking the Back button. You can exit the setup where appropriate by clicking Cancel.
When the installation is complete, click Finish.

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. However, starting with the August 2012 releases (products using NI Installers version 3.1 or later), you may need to perform additional steps before or during a silent installation of NI software.

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, refer to the following KnowledgeBase articles:

For more information on silent installations of individual NI products, refer to KB 4CJDP38M, Automating the Installation of a Single Installer.
For more information on silent installations of suited NI products, such as NI Developer Suite, refer to KB 4GGGDQH0, Automating 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 National Instruments Installer?.
