Fixed: Microsoft Office 2016 installation stuck at 90%, 95% or 80%

Recently I encountered a problem during Microsoft Office 2016 installation. I downloaded the installation package and began installation, but the MS Office 2016 installer got stuck at 90%. I tried again and this time decided to wait more, but even after 30 mins the installation wouldn’t be completed. I tried it several times and sometimes it would get stuck at 95%, sometimes at 94% and sometimes even 82%. I am currently running Windows 10 but I’ve encountered the same installation freezing issue on Windows 7. After digging around various forums, I managed to find some effective solutions which could fix the problem where MS Office installation takes unusually long time to finish. Here is how I fixed Microsoft Office 2016 installation stuck at 90%, 95% or 80%: The methods below can be applied for any Microsoft Operating System i.e. Windows 7, Windows 8.1 and Windows 10.

Microsoft Office 2016 Package

Method 1: Terminating wusa.exe

  • Stop Microsoft Office Installation (which is not responding or stuck)
  • Run task manager (Press ctrl+alt+delete) and click “task manager”
  • Find “wusa.exe” from the list of processes >> Right Click >> Select “End Task”

Try installing Microsoft Office Package again. Wait sometime, and the installation should get past the initial percentage ie,e 90% and jump to 100% until its finally completed.

Method 2: Stop Print spooler service

This one is the method that worked for me.

  • Press windows key + r
  • Type services.msc >> Press Enter
  • Now, find “Print Spooler” under services
  • Right click on it and select “Stop”

Run the MS Office 2015 or Office 2016 installation. Once the installation is completed, you can again start “Print spooler” service.
If your Microsoft Office installation is taking abnormally long time or gets stuck, one of the above methods should fix it. If you have any other solutions for this problem, let us know how you fixed it in the comments.
