What to do when I get an error: "SuperOfficeDB.dll is not working through COM or not registered properly.." while trying to open Microsoft Office document?

Updated on 30 Nov 2021

I have SuperOffice Ribbons for Microsoft Office installed and while trying to open a document I get an error: 

’SuperOfficeDB.dll is not working through COM or not registered properly: System.NullReferenceExeption: Object reference is not set to an instance of an object. at SuperOffice.Ribbon.Common.SOServices.CheckDBComponent() at SuperOffice.Ribbon.Common.SuperOfficeRibbonBase.VerifySOComponentsOk()'

This error occurs if the file SuperOfficeDB.dll is not registered properly on the computer. There are several solutions which could be applied to fix the problem:

  • Make sure the correct SuperOfficeDB.dll file is on the computer.
