NamoRamana 2 Posted July 31, 2019 (edited) When I try to start Interbase db as windows service, it throws and error: Unable to start server: unknown error. However, when I uncheck "Run as.. Windows Service", it does run in as system tray application. I have local admin priviledges on Win10 machine. Have Delphi Rio 10.3.1. Edited July 31, 2019 by NamoRamana Share this post Link to post
