Attempting to install SQL Server Reporting Services on Cluster Nodes with the same instance name fails

When you attempt to use the same instance name for installing SQL Server Reporting Services using the clustered instance, you will receive the following error when attempting to install it the second time:

StandaloneInstall_HasClusteredOrPreparedInstanceCheck

Checks if the selected instance name is already used by an existing cluster-prepared or clustered instance on any cluster node.

Failed

The instance selected for installation is already installed and clustered on computer {ComputerName}. To continue, select a different instance to cluster.

The issue is that SSRS must be two separate installations, one on each node, with two different instance names.  You can, however, share the same report server database using a scale-out deployment.  To set up a Scale-Out Deployment, you can use the following MSDN link:
