topology:unregistered as versioned, but still getting "registered as versioned error"

Discussion created by SRoberts on Apr 7, 2011
I would like to add a feature class to the topology of a featureDataset in ArcSDE (version 10) that was registered as versioned.  I disabled archiving and unregistered the featureDataset as versioned.  I tried to run the "Add featureclass to topology" tool, but get the error "Cannot add a class that is registered as versioned to a topology".  (The feature class and the topology are both in the featureDataset which I just unregistered as versioned)

Thanks for any insight,
