. dll error while loading ABB InformIT calculations extension
I am getting an error while loading ABB InformIT calculations extensions - IT\Calculations\bin\CalculationAction. dll failed to unregister. What could be the possible reason?
Was the system properly shutdown while performing the software installation into Microsoft Windows?
I would stop the system (Config Wizard->maintenance stop, PAS->Stop All, etc.), unregister the DLL manually (see link below), then remove and reinstall Calculations from appropriate media, reboot, then try a new System Extension load/maintain
