Customer had Office 2010 on his computer, and was upgrading to Office 2016 via his GoDaddy Office 365 account. But the installation would fail half way through with error code 30143-37
GoDaddy support said it was because anti-virus was running. We stopped A/V but still encountered the error. I then right clicked on the downloaded setup executable, selected Properties, and clicked to “unblock” the file. That did not help either.
I found a couple of web sites that suggested deleting (or at least renaming) the folder “C:\Program Files\Microsoft Office 15”.
That seemed to do the trick, as I was able to then install Office 365. Note: I did NOT reboot the computer after deleting the folder.
