Revit 2021 Material Library missing

[Anonymous]

Hello, 

When I installed Revit 2021, I didn't select the additional components for 'Medium Image Advanced Material Library 2021'. So now I have revit with no material library installed.

How do I retrieve the Advanced Material Library 2021 without uninstalling and reinstalling revit again?

Thank you for this. 

Why do all the AEC materials have a lock over them? How can I use them?

Simply search for the material you need and add it/them to the document...then you can use/apply to elements in the project

The Lock means that the material library is protected from having materials modified, added, or deleted from its contents. If you create a standard material library for use by several members of a project team, you can lock the library to prevent unwanted changes.
