Why am I getting warnings about missing DLLs when adding a node to a WSFC?

We're getting the following two errors when adding a node to our WSFC.

The node was added successfully, but the 'SQL Server Availability Group' resource type could not be installed on it.
Unable to find 'hadrres.dll' on any of the cluster nodes.

The node was added successfully, but the 'SQL Server FILESTREAM Share' resource type could not be installed on it.
Unable to find 'fssres.dll' on any of the cluster nodes.

This cluster is going to host an AlwaysOn Availability Group. SQL Server 2012 is installed on both nodes, and availability groups are enabled on both. Filestream access is also configured on both. Another curious thing I'm seeing is that my instance on the second node doesn't appear in Configuration Manager.

Anyone know what may be going on here?
