Outlook TYPE_E_LIBNOTREGISTERED / TYPE_E_CANTLOADLIBRARY Error

If you recently uninstalled Outlook 2013 or have a problem with our your Outlook installation then you may encounter the following error message when syncing with gSyncit ...

Error = Internal error. Unable to cast COM object of type 'Microsoft.Office.Interop.Outlook.ApplicationClass' to interface type 'Microsoft.Office.Interop.Outlook._Application'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{00063001-0000-0000-C000-000000000046}' failed due to the following error: Library not registered. (Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED)).

The root issue is that the Version reference for the TypeLib created created by the Outlook installation is pointing to a incorrect value. The following should help correct this issue...

Solution #1:

Step #1 (Fix the Interface)

  1. Access the Windows Registry Editor via Start,  Run,  Cmd,  RegEdt32,  enter.
     
  2. Navigate to HKEY_CLASSES_ROOT\Interface\{00063001-0000-0000-C000-000000000046}\TypeLib
     
  3. Find a '(Default)' entry with the value '{00062FFF-0000-0000-C000-000000000046}'
     
  4. You should find a 'Version' entry. Check that this version matches the value in the following table based on the version of Outlook currently installed.
     
    Outlook Version
    Outlook 2000 9.0
    Outlook 2002 9.1
    Outlook 2003 9.2
    Outlook 2007 9.3
    Outlook 2010 9.4
    Outlook 2013 9.5


 
Step #2: (Fix the TypeLib)

  1. Navigate to HKEY_CLASSES_ROOT\TypeLib\{00062FFF-0000-0000-C000-000000000046}
     
  2. Delete the version keys (e.g. 9.5) for any version of Outlook that is not installed on your system based on the version table provided below. For example, if you are not using Outlook 2013 then remove the "9.5" entry. If you are not using Outlook 2010 then remove the the "9.4" entry. DO NOT DELETE the entry for the version that was configured in Step #1
