Hi,
i have deleted the created database from the SQL Server, uninstalled the previous version of the OpenHistorian and installed the suggested build. The Real Time data on the web application is working perfectly but it seems to display the same error message on exporting data.
I don’t know if it helps but to lessen the volume of data stored i had a unselected a lot of signals from the openHistorian and kept 6 in total. ( 4 Voltage Magnitudes, 1 Frequency measument and 1 Df/Dt measurement); this is the same configuration i did on a different vm when the openHistorian is storing data locally.
