Hi @Micheal Beaton ,
Thank you for your reaching out and welcome to Microsoft Q&A!
I have already uninstalled all MS Office files using "SetupProd_OffScrub.exe" and re-installed MS Office 365 using "OfficeSetup 365 64bit.exe".
In addition to Tom's suggestion, if for some reason the machine is in a bad way, you may need to be more aggressive about the uninstall. From a PowerShell command line.
"(Get-AppxPackage -Name Microsoft.Office.Desktop).Dependencies | Remove-AppxPackage"
then
"Get-AppxPackage -Name Microsoft.Office.Desktop | Remove-AppxPackage"
That will typically throw an error if everything is already removed.
Then to verify that it is indeed removed, this command should return nothing.
"(Get-AppxPackage -Name Microsoft.Office.Desktop).Dependencies"
Feel free to share your issues here if you have any concerns.
Best regards,
Lucy Chen
