Commented Unassigned: Class not exists: NetOffice.OfficeApi.Document [22155]

We are currently using NetOffice for our Microsoft Outlook AddIn.
application.ActiveInspector().WordEditor currently returns null value for Outlook 2010 and throws next exception for Outlook 2013:
Class not exists: NetOffice.OfficeApi.Document at NetOffice.Factory.CreateObjectFromComProxy(COMObject caller, Object comProxy) at NetOffice.OutlookApi._Inspector.get_WordEditor()

According to Microsoft [documentation](https://msdn.microsoft.com/en-us/library/office/ff868196.aspx) WordEditor should return Microsoft Word Document Object Model of the message being displayed.
Seams that NetOffice.Factory.CreateObjectFromComProxy method is trying to create object with wrong class name. It should create NetOffice.WordApi.Document instead of NetOffice.OfficeApi.Document.
