I'm trying to install Microsoft Office 2016 with a 1-user business subscription.
After a variable amount of time displaying the mysterious message "We're getting things ready" the installer .exe file fails every time with this message:
Couldn't stream Office
Sorry, we can't find a required file. Please check that the installation source is reachable, then try again.
Error Code: 30183-1 (-2147012867)
There's no clue at all about what required file is missing, or what installation source is unreachable.
The only actions are, a link to a completely generic installation help page with no relevant info, and a "Close" button.
The closest to Microsoft support on this error is a page for every error code between 3 and 4 saying it might be related to my connection. I've disabled my firewall and tried on multiple connections, but nothing works.
I had a trial version of Office 2016 installed, but it still happens even after completely uninstalling the trial and using Microsoft tools to ensure there's no trace left. There's nothing wrong with my network connection. I've tried restarting and running the installation with no Office software open.
How can I go about fixing this? I'm all out of leads.
