Microsoft Office Install Error 30125-1011 (403)
I am trying to install Microsoft Office 2016 Professional and Microsoft Visio 2016 Standard on a Windows 10 PC. The installation for both fails with the message "Couldn't install" and gives Error Code: 30125-1011 (403). This PC used to have Microsoft Office 2010 Professional installed on it, but it has been completely removed by doing a program uninstall. I also ran the Microsoft Office Uninstall tool (o15-strremove.diagcab) AND manually deleted all keys in the registry under Computer\HKEY_LOCAL_MACHIN

I have turned off my third-party anti-virus & firewall protection (Kaspersky Internet Security). I've rebooted countless times after each attempted solution, but it still refuses to install. I am at a loss as to the cause or resolution. Any ideas?

Interesting. A standard firewall does not block Office installs. At least now you have it installed.

The problem was most likely related to the company firewall. I was able to resolve the issue by bypassing the network firewall and connect directly to the Internet. I wish I had the time to diagnose the firewall settings that prevented the installation from working, but I needed to get this resolved quickly. Suffice it to say, bypassing the network firewall was the answer.
manually deleted all keys in the registry under Computer\HKEY_LOCAL_MACHIN
That may have deleted the office keys needed for reinstall.
Try running DISM and restart to see if that helps. We can go from there.
Open cmd.exe with Run as Administrator and run:
dism.exe /online /cleanup-image /restorehealth
