How to Fix Office 2016 Installation Error 30015-6 (-1)

Solution 1 – Run Fix it

Microsoft is aware that some Office 2016 has some problems, so the company released new Fix-it tool for proper uninstalling the product. So, the first thing we’re going to try is running that tool, and then installing Office 2016 again. Here’s what you need to do:

  1. Download Fix-it tool from this link
  2. Follow instructions from the wizard to properly uninstall Office 2016office 2016 installation error windows
  3. After the installation is done, try to install Office 2016 again:

Some people reported that this fixed the issue, but there are some users who are still facing the issue, as well. So, if you’re unable to install Office 2016 after performing this solution, try some of the following.

Solution 2 – Temporarily Disable Antivirus and Firewall

Maybe your current antivirus prevents Office 2016 from installing. So, disable your antivirus and then try to install Office 2016 again (we cannot tell you exactly how to disable your antivirus, because it varies on antivirus programs). Additionally, you can try to disable Windows Firewall and then try again. If you’re not sure how to disable Firewall, here’s the instruction:

  1. Go to Search, type firewall and open Windows Firewall
  2. Go to Turn Windows Firewall off or on
  3. Go to Turn off Windows Firewall office 2016 installation error

We have to tell you that we don’t completely guarantee you that these fixes will work, as the problem is still ‘young’ and experts still have to work on it. And maybe Microsoft will release an official fix for this problem, we’ll see in the future. The only thing we know for now is that people are frustrated because of the fact that they’re facing the issue right-after the full version of Office 2016 was released.
