.NET 4.0 WinForm - 无法加载文件或程序集或其依赖项之一。不是有效的Win32应用程序

Question

我有一个可以在大多数 Windows 10（64 位）系统上运行的应用程序，但是有 6 台计算机遇到了相同的 BadImageFormatException。应用程序和库以 AnyCPU 为目标。尝试从程序集创建 COM 对象时，出现异常：

无法加载文件或程序集“InfoConnectCOM.Wrapper64.dll”或一个 其依赖项。不是有效的Win32应用程序。 （例外来自 HRESULT: 0x800700C1)

根据包装器的名称，它看起来应该引用 x64 程序集。最近有 30 台计算机以相同方式成像，只有 6 台存在此问题。此外，还有数百台其他 Win10（64 位）计算机没有遇到此问题。

    Private _system As Object
    Private Const IC16AssemblyName As String = "InfoConnectCOM.Interop, Version=1.0.0.0, Culture=neutral, PublicKeyToken=13bff1b6907eadcf"
    Private Sub CreateIC16SystemObject()
        Dim assembly As Reflection.Assembly = Reflection.Assembly.Load(IC16AssemblyName)
        Dim type As System.Type = assembly.GetType("Accmgr.AccmgrSystemWrapper")
        _system = Activator.CreateInstance(type)
    End Sub

程序集是动态加载的，因为我需要代码在不同平台上使用不同版本的软件。

我们已尝试卸载并重新安装 InfoConnect 软件。如果我将代码和库更改为以 x86 为目标，它就会运行。但是，我想避免重新编译所有软件以针对 x86。

关于如何继续解决此问题或为什么只有少数计算机会受到影响的任何想法？

谢谢

原来机器上唯一的 C Redistributable Library 是 32 位版本。 COM Wrapper 是 C 语言，所以当它试图加载 mvscr120.dll 时，会拉出错误的版本。修复已解决问题。
