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

1 64-bit VISA applications are supported for a limited set of instrumentation buses. The supported buses are ENET-Serial, USB, and TCPIP. Logging VISA operations in NI I/O Trace from 64-bit VISA applications is not supported.

Supported Development Environments

NI-VISA for Macintosh supports LabVIEW 2009 or later.

Installed Files and Paths

There are three main locations where NI-VISA installs files.

• The local /Library/Frameworks folder contains the VISA.framework folder. This folder contains all needed headers and supporting Passport libraries that NI-VISA uses.
• In the local /Applications/National Instruments folder, there is an NI-VISA folder. This folder includes the NI-VISA Help, as well as several groups of C examples using NI-VISA. This NI-VISA folder also includes a graphical utility called NI-VISA Configuration to configure VISA options and the VISA Interactive Control (VISAIC).
• Finally, the /Library/Preferences folder contains an NIvisa folder with .ini files. These files are used for NI-VISA settings and status codes.
