This tutorial mainly focus on the settings you have to do in OpenOffice if you choose to download SENIB.zip or SENIB.exe.
In the tutorial it is mentioned that you can install OpenOffice or LibreOffice but LibreOffice is not supported any more so to use SENIB you need OpenOffice.
In the file SENIBwOO.exe all settings are already done, so if you download that file it's not so important to watch this tutorial. Then you just open SENIBwOO.exe and after that the included file manager Q-Dir. From Q-Dir you open 1NewHouse.ods and start using SENIB.
In OpenOffice 4.1.2 comments in cells are not shown when the mouse hovers over them. This is due to a changed setting in OpenOffice. In OpenOffice 4.1.6 this setting is set back to how it should be but if you can't see the comments then this setting can be changed by selecting the checkbox “Tips” on the menu Tools – Options – OpenOffice – General. See picture below.
