There is a more detailed message listed in the ION_Network.log or ION_Data.log file located in the ...\Power Monitoring Expert\Diagnostic folder. This is the error message that is contained in those logs:

*Warning: Irreparable database damage can occur. This procedure should only be performed by users familiar with SQL Server Management Studio. Databases should be backed up prior to performing this procedure.* 

To resolve this, run the script called 'NOM12_ChangeDBOwner.sql' manually in SQL Server Management Studio. This file can be found in the ...\Power Monitoring Expert\system\scripts directory. Then rerun the Installer choosing 'Resume', if you have shut down the Installer, or choose 'Try Again' if the installer is still running.
