它与我在我的应用程序中使用的DLL文件有关。我尝试过使用regsvr 32注册这个DLL文件,但是我做不到。

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

这可能不能解决你的问题,但建议以防万一(我知道我遇到了类似的问题之前,而不是与.NET应用程序)。

如果你是64位机器,则有2个 regsvr32.exe文件; 一个在\Windows\System32 ,另一个在\Windows\SysWOW64

你不能用32位版本注册64位的COM对象,但是你可以做到,反之亦然。我会尝试注册你的DLL与两个regsvr32.exe文件显式(即键入“ 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...

什么是你的应用程序的目标平台?我认为你应该设置平台x86,不要设置它Any CPU
