Problem printing with Apprentice 2016

[Anonymous]

Hi,

  We are upgrading to Vault and Inventor 2016 on the weekend.  I just discovered that one of my custom projects is acting up with the 2016 version of Apprentice .

I have attached my Visual Studio project for reference. It is a verys simple project just to illustrate this error.  I would be very grateful if somebody could come up with a solution.  (There is one other post on the forum here without a solution).

Just to follow up on this, our reseller helped us get this resolved.  Unfortunately I am not 100 percent sure on one specific thing that fixed it.  I had been referencing the Autodesk.Inventor.Interop.dll library.  We changed that to the .COM Autodesk Inventor's Apprentice Object Library.  We also switched the target framework from .Net 4.5 down to 4.0 and then back up to 4.5 again.  After that we 'cleaned the solution'.  I believe one or all of these items is what helped us get back on track.  Hopefully this can help somebody else too!
