关于LabVIEW 2014的详细信息，请在LabVIEW中单击帮助»LabVIEW帮助，查看LabVIEW帮助。
选择帮助»查找范例，打开NI范例查找器。用户可依据应用程序修改范例，或在创建的VI中添加范例。
大多数NI产品都可通过命令行自动安装，通过设置命令行参数完成安装程序用户界面或对话框的设置。从2012年8月发行的版本（NI Installers 3.1或更高版本）开始，实现无人值守的NI软件安装时需要作一些额外的设置。
如待安装的NI产品依赖于Microsoft .NET 4.0，则在启动NI软件安装之前，.NET安装程序会首先启动并在完成后提示重启。如需避免上述情况，可在安装NI软件之前单独安装.NET 4.0。
更多详细信息，见下列知识库文章：
在Microsoft Windows 8.x上安装NI软件时，应用视图上会增加一些图块，作为指向各个NI应用程序（比如NI LabVIEW、Measurement & Automation Explorer (NI MAX)和NI启动器）等软件的快捷方式。
“NI启动器”可用于定位和启动计算机上已安装NI产品。其功能类似于Microsoft Windows以前版本的“开始”菜单。如需打开“NI启动器”，可在应用视图中单击NI启动器图块。“NI启动器”将启动桌面并打开一个菜单，其中包含一系列NI产品。单击产品名称可启动NI产品。
| 注： 在Microsoft Windows 8.x中，桌面上不再包括NI MAX快捷方式。可通过应用视图或NI启动器启动NI MAX。 |
您可将常用的NI应用程序（例如，NI MAX）固定到开始屏幕或桌面任务栏：
| 当前应用程序环境 | 图标位置 | 固定应用 |
| Windows 8.x桌面 | 桌面任务栏 | 右键单击应用程序并选择固定到任务栏 |
| Windows 8.x桌面 | 开始屏幕 | 右键单击应用程序并选择固定到开始屏幕 |
| Windows 8.x开始屏幕 | 桌面任务栏 | 右键单击应用程序并从屏幕底部的菜单栏选择固定到任务栏 |
如需在“开始”屏幕中查找特定的应用程序或相关文件（例如，文档），右键单击开始屏幕的任意位置，选择所有应用 (Windows 8)，或在屏幕左下方单击向下箭头(Windows 8.1)，在应用视图中查看全部已安装文件。
关于Windows 8.x系统NI支持的更多信息，见ni.com/windows8。
2016年7月1日起，LabVIEW将不再支持Microsoft Windows Vista、Windows XP和Windows Server 2003。2016年7月1日以后发布的新版本LabVIEW将无法在Windows Vista、Windows XP或Windows Server 2003上安装运行。关于NI应用程序软件产品生命周期的更多信息，请访问ni.com/info并输入以下信息代码：
