After deploying a scorecard to Reporting Services, RS reports that "ScorecardDPE" is not installed or configured properly.

After uninstalling and reinstalling, the following error messages are observed in the RS log file:

- ScorecardDPE does not implement iExtension or System.Data.iDbConnection

- An attempt has been made to use a data extension 'ScorecardDPE ' that is not registered for this report server.

Report Services 2005 is installed.
