它与我用于我的应用程序的Dll文件.我试图使用regsvr32注册这个DLL文件但我无法做到.

DLL:AxInterop.DHTMLEDLib.dll & Interop.DHTMLEDLib.dll

有没有人对这个例外有所了解？

Answer 1

您的应用程序的目标平台是什么？我认为您应该将平台设置为x86,不要将其设置为Any CPU.

Answer 2

这可能不是你的问题的解决方案,但建议以防万一(我知道我之前遇到过类似的问题,但没有使用.NET应用程序).

如果您使用的是64位计算机,则有2个 regsvr32.exe文件; 一个在\Windows\System32 ,另一个在\Windows\SysWOW64.

您不能使用32位版本注册64位COM对象,但您可以反之亦然.我试着regsvr32.exe明确地用两个文件注册你的DLL (即输入" C:\Windows\System32\regsvr32.exe /i mydll.dll"然后" C:\Windows\SysWOW64\regsvr32.exe /i mydll.dll"),看看是否有帮助......

Answer 3

当我将框架从4.5更改为4时,我得到了与vlc组件相同的错误.但是当我将平台从Any CPU更改为x86时,它对我有用.

Answer 4

我今天偶然发现了一个 DLL，我知道它在我的 VS2013 项目中运行良好，但不适用于 VS2015：

去： Project -> XXXX Properties -> Build -> Uncheck "Prefer 32-bit"

这个答案已经过期了，可能不会有任何好处，但如果你。但我希望有一天这会对某人有所帮助。
