Have you received a docx file but can’t open it? Learn how to open docx files with this Word Tip!
Docx is the default file extension in Microsoft Office Word 2007.
To open docx files, you need to have Word 2007 OR the compatibility pack or a Word viewer installed on your computer.
These instructions work for docx and docm files, but you will not be able to open dotx and dotm files unless you are running Word 2007.
Click the statement that best describes your set up. The link takes you to a short tutorial:
Do you already have Microsoft Word 2007 installed? Just double-click the file icon to open and edit the file. Still can't open the document? Read the troubleshooting tips on this page for help.
If you don't have Word 2007 installed, you can download the Microsoft Word free trial, then use it to open the docx file.
Or, if you need to open a docx file but don't have Word 2007 installed and do not want to download the free trial, see the Word Tip, How to Open docx files Without Word 2007.
Sometimes you cannot open docx files even if you have Word 2007 (or the compatibility pack or viewer) installed.
Try these troubleshooting steps if you can't open a docx file with Word 2007 or after installing the compatibility pack, and you need to recover your data.
If a pop-up window appears asking for a password, you will not be able to open the file without first entering the correct password.
A Word document password is encrypted so you won't be able to crack it. You will have to get the password from the author of the file.
Is this your own file but you forgot the password? Well, you are out of luck unless you have an unencrypted version in a backup file or attached to an email.
Tip: Always write down the password somewhere, even if you think you will remember it.
If the file will not open, it may have an incorrect file extension, or it may be corrupted.
Sometimes people type in the wrong extension when saving a file. Try changing the extension from docx to doc or vice-versa to see if it will open. (You might also want to try docm, dotx, or dotm.)
Didn't work? Try a repair.
Open and Repair a Corrupted Word document |
You can repair a file while opening it by following this procedure:

Remember to save the file before closing it or the repair will be lost.
