Microsoft Office is constantly working on improving its software. However, there may be times when Word simply refuses to start. Here are a few ways to get Word back on track.
Update Microsoft Office
It is always a good idea to keep your software up-to-date, because companies are constantly providing solutions for bugs and vulnerabilities that affect the performance of the application.
Since Office 201
The good news is that you can do this from any of your Office apps. So if Word does not start, you can update via Excel, PowerPoint or other Office programs that you have.
To update, open your Office app, click the "File" tab, and then click "Account" at the bottom of the left panel.
Click in the "Product Information" section on "Update Options" next to "Office Updates." From the drop-down menu, select "Update Now."
Office checks for and applies updates. After the update is complete, a success message is displayed. 
Now try to open Word, if you still have problems, something else is going on, let's try a few other steps.
Repairing Office from the Control Panel on Windows
Before deleting registry keys or the global template file, make sure that the Windows Repair utility is sufficient.
Right-click on the Windows icon in the taskbar and then select "Apps and functions" from the menu that appears
The "Settings" window appears. Scroll through the list and select your Office app and then click on "Change".
The following message that you see depends on the version of Office that you have. In the click-to-run version (such as Office 365), select "Online repair" and then "Repair". If you are running an MSI copy (you have used installation software to install it on your computer) from Office, select "Repair" and then "Continue".
After the repair is complete, restart the computer and try starting Word. If this hasn't solved the problem, it's time to dig a little deeper.
Use the switch
/ a Windows
When you use the switch
/ a to start Word, it starts in its original state. It therefore prevents add-ins and general templates, such as Normal.dot, from loading automatically.
If you successfully start Word with this method, it provides a great starting point for troubleshooting, since it is probably an add-in or template that causes the problem.
You can also start Word in safe mode if you type
/ safe instead of
/ a in the step below. This also starts Word without add-ons, templates and other adjustments.

To try press this method on the Windows key, type "Run" and press then "Enter". The "Run" dialog box appears. Type here
winword / a and then click "OK".
If Word starts successfully, the problem is in the Office Startup Folder or Registry information
Reset user options and registry settings in Word on Windows
Abnormal behavior becomes common caused by formatting, options and / or custom settings in Word. If you use Registry Editor to change the registry, you can reset it.
Standard warning: Registry Editor is a powerful tool; if you use it incorrectly, your system may become unstable or unusable. However, this is a fairly simple tutorial and you should not have any problems if you follow the instructions.
However, if you have never worked with Registry Editor before, you may want to read about it before you begin. In addition, consider backing up the registry (and your computer) before making changes.
Close all Office applications first. Then press Windows + R to open the "Run" window. Type here
Regedt32.exe and click "OK".
The Registry Editor is opened. Navigate to the location of the key that you want to delete; it appears in the following file path:
HKEY_CURRENT_USER Software Microsoft Office 16.0 Word
Note that "16.0" in the file path is probably different depending on the version of Office you have. If you use Office 2013, search for "15.0". Microsoft offers an extensive list of key locations if you need more help.
Then select the key that you want to delete, and then click Edit> Delete.
Click "Yes" in the dialog box that appears to remove the key.
You will be prompted to go through the installation process the next time you start Word.
Restoring Word to Factory Defaults on Mac
You can also perform a factory reset for Word on a Mac. To do this, close all Office applications and open "Finder". Press Shift + Command + G to open the "Go to folder" search box.
Type the following:
~ / Library / Group Containers /UBF8T346G9.Office/User Content / Templates
Click "Go". Here you can see the Normal.dotm file; move it to your desktop.
Then open the "Go to folder" search box again (Shift + Command + G). This time, go to the following file path:
~ / Library / Preferences
Click on "Go". Locate the com.microsoft.Word.plist and com.microsoft. Office.plist files and move them to your desktop. Restart Word.
Office automatically recreates these files, so don't worry.
Replace the Global.dot Global Template File on Windows
Your global template file contains macros, AutoText entries, and formatting settings, which often prevent Word from starting properly. If you replace this file, any issues caused by damage to the previous file will be removed. However, this comes with a warning: you must go back and reconfigure all your custom settings.
Press the Windows key to replace the Normal.dot file (or the Normal.dotm global template). Type "cmd" in the Windows search box, and then press "Enter" to open the command prompt.
At the command prompt, type the following command:
Ren% userprofile% AppData Roaming Microsoft Templates OldNormal .dotm Normal.dotm
Press "Enter" . When you are finished, you can safely close the command prompt.
When you start Word, you will be prompted to continue the installation process.
These are just a few of the ways to diagnose and resolve Word startup issues. However, there may be other causes that are not covered here.
