我已在我的 Visual Studio 2010 应用程序中嵌入了 WMP 控件，该应用程序可在 Windows 7（框架 4.0）上运行，但在 winXP 上安装该应用程序时，出现以下错误：

System.IO.FileNotFoundException: Could not load file or assembly 'Interop.WMPLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

我想这是一个参考问题，但我添加了对 WMP 库（axinterop.wmplib.dll 和 interop.wmplib.dll）的引用。WMP 在 XP 机器上工作，但从我的应用程序调用时不能。

我现在已经在网上搜索了 5 天并更改了引用，并在 XP 机器上重新安装了媒体播放器，但没有任何效果。

谢谢你的帮助。

将构建配置更改为 x86 而不是 AnyCPU。这会将其构建为 32 位应用程序，并且 Interop.WMPLib 可以正常工作。问题是，至少据我所知，没有 64 位的 Interop WMPLib 版本。
