这是我第一次在这里发布我的问题（我曾经在任何地方找到答案，但这让我感到疯狂）。对于我的新工作，我需要使用FlashBuilder（Adobe）在Flex中编程。我的合作伙伴正在使用Windows 8，但他们给我的企业计算机已经运行Windows 10。我一步一步地按照他们用来安装所有内容的相同手册，但我得到以下错误：

我尝试安装下一个插件：org.w3c.css.sac.source_1.3.1.v200903091627.jar，但我没有做任何事情。我试图在互联网上搜索，但我无法找到解决方案。我们认为问题在于操作系统，因此它们与我的环境之间存在着独特的区别。
如果您已经遇到此错误或者您知道任何解决方案，我会非常感激。
非常感谢， 涓。
