Exception from HRESULT: 0xC0048021 in DMF AX 2012 R3

If you're using Excel 2013 like I am, the problem is caused by tge DMConfig XML file.

Go to the DMConfig.xml file in the Microsoft Dynamics AX\60\DataImportExportFramework  folder and replace the PipelineComponentInfo_Multicast, PipelineComponentInfo_ExcelSource and  <PipelineComponentInfo_ExcelDestination> nodes by the following:

  <PipelineComponentInfo_Multicast>
    {33D831DE-5DCF-48F0-B431-4D327B9E785D}
  </PipelineComponentInfo_Multicast>
  <PipelineComponentInfo_ExcelSource>
    {9F5C585F-2F02-4622-B273-F75D52419D4A}
  </PipelineComponentInfo_ExcelSource>
  <PipelineComponentInfo_ExcelDestination>
    {90E2E609-1207-4CB0-A8CE-CC7B8CFE2510}
  </PipelineComponentInfo_ExcelDestination>
