After I installed a Microft Office 2016 on ** a SharePoint Server 2016 (Win 2016), the central admin had error **503 Service Unavailable. I opened Windows Service and saw that only one a SharePoint Administrator Service was started and I tried to start SharePoint Timer Service but it didn't start (Error 1053: "The service did not respond in a timely fashion"). Please help me.

Many thanks

To fix this issue, Install Office 2016 updates and then Repair the Microsoft SharePoint Server 2016 from Control Panel --> Programs and Features

Looks like we faced the same issue after installing MS Office 2016 64bit on SharePoint 2016 application server. The fix was found in this article: SharePoint 2016 Forgets Where It’s Installed After Update.

If it looks like everything on a SharePoint server suddenly stops working, make sure the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\16.0\Location points to the right place.

In our case the value of that key was empty.

I believe simply repairing SharePoint server installation also would help.

Make sure All application pool are running in IIS. Sometimes this can happen. If application pool is down you get 503 error message.
