Node of type... can not be resolved

Hi all,
can someone help me?
i have a problem with the packages i have downloaded.
Dynamo cannot read the path.
please see attached the images.


thanks for your help


I think this has been replaced by the OOTB node Element.ElementType


the problem is not the proper node… is the message that i have in several nodes

This message usually shows up when they are not icluded in any of the installed packages. It could be, as @m.rijsmus said, because it was there in an older version but not any more.

If not you are probably missing a package.
