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：NI序列号Serial Number生成激活工具NI License Activator，LabVIEW/VBAI/VDM/VAS等软件模块工具包破解工具不限版本http://visionbbs.com/thread-490-1-1.html

视觉论坛的各种NI资源，除了视觉相关的模块有使用外，大部分的都不会使用，仅提供资源不提供技术支持。资源的下载地址一般会同时提供NI官方和百度网盘的地址。某些工具包NI地址失效或没有NI地址，只能使用百度网盘地址；如果百度网盘地址失效过期，可联系论坛客服更新。NI的服务器在美国，有时候速度很慢或下载容易出错，这样会造成安装时各种错误而无法安装。建议在下载完成后，对下载资源做校验和(NI一般会提供MD5或SHA256等)验证，与官方或视觉论坛提供的校验和对比，一致就可以安装；如不一致，则需要重新下载。视觉论坛早期下载上传的资源，基本上都是正常下载的资源；2019后下载的资源，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。校验和工具下载地址：文件Hash计算器FHash，文件校验和验证下载文件正确性验证，MD5值计算、SHA1值计算、SHA256值计算、CRC32值计算http://visionbbs.com/thread-26524-1-1.html

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 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?.

How to Use NI Software with Microsoft Windows 8.x

When you install NI software on Microsoft Windows 8.x, 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.

Using NI Launcher

NI Launcher helps you find and launch installed NI products. It provides you with a method of finding NI products similar to the Start menu in previous versions of Microsoft Windows. To use NI Launcher, click the NI Launcher tile in the Apps view. NI Launcher launches the desktop and opens a menu containing a list of NI products. Click any NI product to launch it.

Note  NI MAX does not appear as a desktop shortcut when installed on Microsoft Windows 8.x. You can launch NI MAX either from the Apps view or from within NI Launcher.

Pinning Frequently Used Applications

For convenience, you can pin your most-used NI applications, such as MAX, to either the Start screen or the Taskbar on the desktop, as necessary:

[talbe]
[tr][td]Current Application[/td][td]Icon Location[/td][td]Pin to Action[/td][/tr]
[tr][td]Windows 8.x Desktop[/td][td]Desktop Taskbar[/td][td]Right-click application and select Pin to Taskbar[/td][/tr]
[tr][td]Windows 8.x Desktop[/td][td]Start screen[/td][td]Right-click application and select Pin to Start[/td][/tr]
[tr][td]Windows 8.x Start screen[/td][td]Desktop Taskbar[/td][td]Right-click application and select Pin to taskbar from the menu bar on the bottom of the screen[/td][/tr]
[/table]Finding All Programs

If you want to find a particular application or related files, such as documentation files, from the Start screen, you can access all installed files from the Apps view. To get to the Apps view, right-click anywhere on the Start screen and select All apps (Windows 8.0) or click the down arrow on the bottom left of the screen (Windows 8.1).
