If you observe the error message 'Missing Module "WonderwareHistorian"' upon starting your Geo SCADA server database in newer versions, it signifies that the necessary 'AVEVA Historic Data Export' module is not currently installed or enabled.

To rectify this issue, shut down the Geo SCADA server, then navigate to your Geo SCADA installation files and initiate a modification of the existing installation. Within the Server tree, locate and enable the 'AVEVA Historic Data Export' feature. Complete the remaining steps of the installation to apply the changes.
