I’m unable to install KB5002677 on our Office Online Server. The installation fails with a generic MSI error:
Event Log:
“Product: Microsoft Office Web Apps Global Components – Update ‘Security Update for Microsoft Office Online Server (KB5002677) 64-Bit Edition’ could not be installed. Error code 1603.”
Log File:
“Assembly Install: Failing with hr=80070005 at RemoveDirectoryAndChildren, line 393.”
Does anyone have any ideas on how to resolve this?

After installing this update, when I try to open office content (excel-word-etc.) from sharepoint, I get the error “We couldn’t find the file you wanted. It’s possible the file was renamed, moved or deleted.” Is it related to the update or is there a different situation?
