Incompatibility with the latest Excel build?

Hi Support,

I have a customer with the latest Excel build version 15028.20228 released on the 20/04/2022 having problems to open my workbook - customer reports he chooses one of the three options such as “Original Workbook” and nothing happens. Can you please check if in fact there is a problem related to the latest Excel version?

Thanks

15028.20228 is not the latest one. Ask your customer to update to latest 16.0.15128.20178. Microsoft seems to have fixed some issues with add-ins.
