---------------------------------------------------------
We are an organization with over 200 users and are currently using Microsoft Office 2013 (Click-to-run install via Office 365 portal), we have noticed that in Excel when we apply the monthly Office update, the add-in (e.g. Analysis Toolpak) would stop working with the following error message displayed.
I tried updating from 15.0.4631.1004 to 15.0.4641.1003, 15.0.4641.1003 to 15.0.4649.1004, they all gave the same results.
I have checked the captioned file path and it is indeed missing, I think the update mechanism messed up the add-in somehow, a full re-install would fix it as quick or online repair is not doing the trick. This is not the only add-in it is affecting as there are some 3rd party add-ins are affected as well.
Please advise how we can fix this without needing to re-install Microsoft Office. Thank you!
