Has anyone got this working in ACAD2012 or 2013? Trying to NETLOAD the respective DLLs I get the same error message in each (this is from 2012; 2013 with the different DLL is virtually identical):
Cannot load assembly. Error details: System.IO.FileLoadException: Could not load file or assembly 'file:///C:\Users\byr59172\ACADDB\LISP\lfilterio\LayerFilter18a.dll' or one of its dependencies. Operation is not supported.
