Uninstalling SQL Server 2005 64-bit in Clustered Environment

I am running into an issue trying to uninstall SQL Server 2005 64-bit.  It hangs at the same point: Removing backup files.  I then get a message that, "The setup has encountered an unexpected error while Completing Commit.  The error is: The cluster resource cannot be moved to another group because other resources are dependent on it."  The instance that I am trying to uninstall is in a cluster hosting two other SQL Server installations.  I have tried a few combinations when attempting to uninstall: running the cluster group containing the server I am uninstalling on a different cluster node than all the other cluster groups; running them all on the same node.  The only one I haven't tried is moving the Cluster Group containing the IP address of the cluster, cluster name, etc to another node while running the other groups on the other node.  Has anyone run into this issue?  Each of the nodes has been rebooted several times during these attempts and we are using Windows Server 2003 Clustering.  Again, the hang happens at the same point every time.   The exact error(s) from the even log are as follows:

Product: Microsoft SQL Server 2005 (64-bit) -- Error 29528. The setup has encountered an unexpected error while Completing Commit. The error is: The cluster resource cannot be moved to another group because other resources are dependent on it.
