（嵌入式）SWF 是否会通知用户是否需要升级 Flash？
如果 swf 适用于 flash 播放器 9，但用户只安装了播放器 8，用户是否会获得自动升级播放器的选项？
if the swf is for flash player 9 but the user only has player 8 installed, will the user get an option to upgrade his player automatically?

简短的回答：是的！
我认为自从 Flash Player 7 Macromedia 添加了快速安装和 Flash Player 检测套件。您可以在这篇旧文章 http://www.adobe 中了解更多相关信息。 com/devnet/flashplayer/articles/express_install.html。
目前最简单的方法是使用 swfobject。甚至还有纯 html 或 < a href="http://code.google.com/p/swfobject/downloads/detail?name=swfobject_generator_1_2_air.zip" rel="nofollow noreferrer">空气。
这个想法是，你有一个expressInstall.swf来处理安装和一些JavaScript来进行检测和所有这些。 SWFObject 已经内置了该功能，只需检查生成器中的“快速安装”选项即可。

Short answer: yes!
I think since Flash Player 7 Macromedia added Express Install and the Flash Player Detection Kit. You can read more about that in this old article http://www.adobe.com/devnet/flashplayer/articles/express_install.html.
Easiest way these days is using swfobject. There are even code generator in plain html or air.
The idea is, you have an expressInstall.swf which handles the install and a bit of javascript that does the detection and all that. SWFObject already has that built-in, just check the Express Install option in the generator.
