I am receiving a large error when trying to edit an Interaction Template in NAV 2013. The error is (in part) Microsoft Dynamics NAV
---------------------------
Compilation of assembly 'C:\ProgramData\Microsoft\Microsoft Dynamics NAV\70\Server\MicrosoftDynamicsNavServer$DynamicsNAV70\assembly\Codeunit5054_171.dll' failed. This can be caused by differences between binaries in your installation or your database. Ensure that all installation components are consistent and up to date. Error details: c:\ProgramData\Microsoft\Microsoft Dynamics NAV\70\Server\MicrosoftDynamicsNavServer$DynamicsNAV70\source\Codeunit\Codeunit5054.cs(450,68) : error CS1061: 'bool' does not contain a definition for 'InvokePropertySet' and no extension method 'InvokePropertySet' accepting a first argument of type 'bool' could be found (are you missing a using directive or an assembly reference?)
And then continues to show different line number combinations of the same error throughout codeunit 5054.
Looking at the codeunit it might be a missing Office automation DLL. Does anyone know if there's a prerequisite?
Windows 7, NAV 2013 vanilla, Office 2010
Thanks very much
