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

Error = "A Outlook component failed to load due to a problem with the Outlook installation"

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 their is a problem with the Outlook installation Common Object Model (COM) interface where the version referencefor the TypeLib entry set by the Outlook installation is pointing to a incorrect value/version or that version does not point to a correct location. The following steps should help correct the most common cause of this issue issue. If you continue to have issues then you may beed to reinstall Microsoft Outlook. Repairing the Outlook installation does not fix this issue so a reinstall is suggested.

   HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Classes\Interface\{00063001-0000-0000-C000-000000000046}\TypeLib

3. Find a '(Default)' entry with the value '{00062FFF-0000-0000-C000-000000000046}'
