You need to:(1) Evict the standalone node from the WSFC cluster
(2) Install the sql on that node
(3) Add the node back to the cluster.
Be very careful here, when you introduce an FCI into a cluster that is to be used for AlwaysOn Availability groups a number of restrictions apply.
The cluster is checking existing groups and has found that a clustered instance of SQL Server already exists on the drive\volume V:\
What happens if at a later date an administrator comes along and runs the add node wizard on one of these cluster nodes?
