vla-GetInterfaceObject in Acad 2004?

[GARYNTX]

This worked fine in Acad 2002 but doesn't work in Acad 2004.

(setq LayerStateObject (vla-GetInterfaceObject (vlax-get-acad-object) "AutoCAD.AcadLayerStateManager"))

I get this error instead

; error: Automation Error. Problem in loading application

Append a ".16" to the end of the string. This is documented in the ActiveX reference.

Try

(setq LayerStateObject
(vlax-invoke-method
(vlax-get-acad-object)
'GetInterfaceObject
"AutoCAD.AcadLayerStateManager.16"
)
)
