ZyDocumentConverter Problem (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY)

SYMPTOMS

You observe in Legal Processing that the TIFF Producer does not function. All actions fail with message: 'Unable to cast COM object of type 'ZyLAB.ZyIMAGE.Interop.ZyDocumentConverter.DocumentConverterImplClass' to interface type.

'ZyLAB.ZyIMAGE.Interop.ZyDocumentConverter.IDocumentConverter'.

This operation failed because the QueryInterface call on the COM component for the interface with IID '{2645BE87-9387-48BC-8A17-DFF3A596BD75}' failed due to the following error: "Error loading type library/DLL:  Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY)). ---> Unable to cast COM object of type".

CAUSE

The registry could contain an invalid link of a previous version and points to the 64 bit version of zydocumentconverter.dll whereas it should point to the 32 bit version of the zydocumentconverter (please note that the folders use the 8.3 notations so they will appear like this: C:\PROGRA~2\ZyLAB\INFORM~2\Bin\ZYDOCU~3.DLL).

RESOLUTION

Open the registry on the Legal prcessing server:

• Open the registry editor.
• Open the following registry key:  HKEY_CLASSES_ROOT\TypeLib\{3D364FFE-733E-4BBA-A254-2D73770A1E9D}\1.0\0\win32
• Modify the registry key value so it points to the 32 bit Windows Registry Editor Version 5.00
  
  [HKEY_CLASSES_ROOT\TypeLib\{3D364FFE-733E-4BBA-A254-2D73770A1E9D}]
  [HKEY_CLASSES_ROOT\TypeLib\{3D364FFE-733E-4BBA-A254-2D73770A1E9D}\1.0]
  @="ZyDocumentConverter 1.0 Type Library"
  [HKEY_CLASSES_ROOT\TypeLib\{3D364FFE-733E-4BBA-A254-2D73770A1E9D}\1.0\0]
  [HKEY_CLASSES_ROOT\TypeLib\{3D364FFE-733E-4BBA-A254-2D73770A1E9D}\1.0\0\win32]
  @="C:\\PROGRA~2\\ZyLAB\\INFORM~2\\Bin\\ZYDOCU~3.DLL"

• You can copy and paste the location into a file explorer to verify which folder it actually points to.
