Answer 1

的Microsoft.SqlServer.DTSRuntimeWrap.dll可能不是在GAC，這意味着它必須被複制在您的Web應用程序的bin文件夾中或手動添加到您計算機的GAC（例如，使用GACUTIL.exe）。你可以在C:\Program Files (x86)\Microsoft SQL Server\100\SDK\Assemblies\中找到它。如果您從Visual Studio項目中的位置引用它，那麼您可以在複製本地到真的參考的屬性中設置該選項。

請注意，此DLL可能不是可再發行的，因此您可能必須在運行該應用程序的任何Web服務器上實際安裝SSIS，以便不違反SSIS許可，但您必須驗證該內容。

如果這是Web應用程序的一部分，則需要從IIS的應用程序池啓用運行32位應用程序。這將解決您的問題。
