  • Hi Mohnish Khiani,

    >> an exception of type "system.runtime.interopservices.COMException" occurred while attempting to launch entity data model wizard. the exception message is: error HRESULT E_FAIL has been returned from a call to a COM component.

    Regarding to the error message you provided, which seems to be related to the Entity Framework issue.  So please try to link to "Visual Studio Setup and Installation" forum and "ADO.NET Entity Framework and LINQ to Entities" forum.  

    Additional there are some workarounds in this thread with the same error message as yours. please refer to the replies from here.

    If you have any concern, please feel free to let me know.
