error C2653: “MSXML”: 不是类或命名空间名

jaishe

我想做一个Palette， 以下用ARX在自动生成的代码 ，直接编译都不通过提示：
myPalette1.cpp(31): fatal error C1083: 无法打开类型库文件: “msxml.dll”: No such file or directory
网上找资料说windows7不再是MSXML了，而是MSXML6，我直接改成MSXML6名字，编译报错又会提示：: error C2653: “MSXML”: 不是类或命名空间名称

有没有那个大神也遇到过这样的问题啊。或者有知错怎么解决的提点一下，谢谢。
（我的环境是：objectArx 2018 + Vs2015 + Windows 10）
