Issue with Interop dll

[stuart.lamb]

Hi folks

I'm looking to use the Apprentice Server with VB.NET to summarise iProperties on a large number of files. I have added the interop reference from C:\Program Files\Autodesk\Inventor 2018\Bin\Public Assemblies, however I get a 'module could not be found' error on the New Inventor.ApprenticeServerComponent command.

There are no build errors so I am guessing this is an issue with the .dll itself. Are there any solutions to try here besides a fresh install of Inventor?

Thanks, the solution was to specify x64.
