I'm triying to register "Interop.Microsoft.Office.Interop.Excel.dll" in my Windows 2003 Server but when execute the regsvr32 command i have this error:

"Interop.Microsoft.Office.Interop.Excel.dll was loaded, but the DllRegisterServer entry point was not found. This file can nto be registered."

How i can register this dll?

Thanks in advance


There's an answer here. Hope it helps.


It might be because the dll doesn't have a DllRegisterServer entry point.

This is a .NET dll, NOT a COM dll, and so you don't regsvr32 it. Instead you need to install the Visual Studio Tools for Office from e.g. here.
