Users of the Microsoft Dynamics NAV Windows Client are suddenly running into error messages about a Document Creator assembly or file not being found. What can we do about this? We are unable to activate the stand-alone Document Creator Designer. What should we do? What is the syntax we can use for expressions (e.g., for the VisibleExpression property)? Is Document Creator (support) future proof? How about a Classic Report and RDLC Report Layout Converter?
