We have gathered these methods and presented them step-by-step so make sure you follow the solutions below in order to successfully resolve the problem.
What Causes the “Microsoft Office Professional Plus 2016 Encountered an Error during Setup” Message?
The list of all possible causes is not so long but it definitely contains everything that might have gone wrong on your computer which causes the installation to fail each time. Make sure you check out the list below as it will help you identify the suitable method more quickly:
Solution 1: Uninstall all Office-related Programs and Delete its Data in Task Scheduler
This is the first method you should try out as it’s probably the one most users found successful as it has worked in their scenario and it should also work out for you. Also, uninstalling all Office-related programs is a good way to start resolving the problem even without the second part. Still, follow the instructions in this article closely and check to see if the “Microsoft Office Professional Plus 2016 encountered an error during setup” error message still appears. The second part of the solution is related to Task Scheduler.
Solution 2: Delete a Registry Entry
This method should be tried out only after you have tried to resolve the problem using Solution 1 and it has failed to work. Some users complained that the method above didn’t help and they only managed to resolve the problem by deleting a certain registry entry related to Task Scheduler and Microsoft Office. Also, sometimes there is no Office folder in Task Scheduler but the folder is available in registry. Check it out below! HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Schedule\TaskCache\Tree\Microsoft
Solution 3: Rename the Microsoft Help Folder
Renaming the Microsoft Help folder inside the ProgramData folder will effectively cause Microsoft Office installation to recreate it and possibly remove all faulty or broken files. This method is simple and it has helped users who tried out other methods and failed. If it doesn’t work, try recreating the Solutions 1 and 2 after performing the steps below: C:\ProgramData
Solution 4: Install Microsoft Office in Clean Boot Mode
There are various other programs and services which can affect the installation of the Microsoft Office suite. In most cases, the cause is the antivirus you have installed and you can try disabling it while the installation runs. However, to make sure nothing can interfere with the installation, we recommend you clean boot which will disable all non-Microsoft programs and services from starting up. After you finish successfully, you can return back to normal mode.
