Hi,
I'm Tim, an Independent Advisor here and a Microsoft user like you. I don't work for Microsoft and do not have access to any of your data on their system.
I would consider using an online repair first to resolve any installation errors:-
Please right click on the start button located on your task bar.
Select apps and features
Select the Microsoft Product you wish to modify, in this case either Outlook or Word but this procedure will repair the whole installation.
Depending on your version of Office you will either be asked “How would you like to repair your office programs” Select Online repair.
Or either Change your installation, select repair and then continue.
The below link is a Microsoft Support Document that you can refer to if needed. An online repair can take a considerable amount of time which is completely normal.

I hope this information helps. If you have questions, please let me know and I'll be glad to assist you further or If you find it helpful, you can mark this comment as the answer.
Kind regards
Tim
