Question

我有一个适用于大多数Windows 10（64位）系统的应用程序，但有6台计算机正在获得相同的BadImageFormatException。应用程序和库的目标是AnyCPU。尝试从程序集创建COM对象时，我得到异常：

无法加载文件或程序集“InfoConnectCOM.Wrapper64.dll”或其中一个它的依赖关系。不是有效的Win32应用程序。（例外 HRESULT：0x800700C1）

基于包装器的名称，它看起来应该引用x64程序集。最近有30台计算机以相同的方式成像，只有6台有这个问题。此外，还有几百台其他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。如果我将我的代码和库更改为目标x86，那么它就会运行。但是，我想避免重新编译所有软件以定位x86。

有关如何继续排除此故障或为何只会影响少量计算机的任何想法？

原来计算机上唯一的C Redistributable Library是32位版本。 COM包装器在C中，因此当它试图加载mvscr120.dll时，错误的版本被拉出。修复解决了这个问题。

.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
