How to fix the "Microsoft Office cannot open this file because part of it is missing or invalid" error

Symptom - Microsoft Office cannot open this file

This error message, “Microsoft Office cannot open this file because of a missing or invalid component,” appears when you try to open a document created with an older version (like 2007 or 2003) of the software.

Damaged file

This error usually occurs when there was a problem while updating or saving the file. If your computer was shut down or crashed while you were saving the file, or Microsoft Word was writing to the disk, the file may be corrupted.

Storage failure or malware

Most newer versions of Microsoft Word reduce the likelihood of corruption by autosaving to a new location rather than overwriting the currently open document. Even if you follow all the safety steps, you might still see a disappointing warning that your Word file is corrupted or damaged.

In some cases, the unexpected behavior might be related to faulty sectors on the storage device. Also, malware threats can lead to Word file corruption, especially when the malware is severe enough to cause system crashes and interfere with files.

To avoid this, make sure you back up your data regularly. You might feel frustrated when you cannot access an important document. However, there is no need to worry too much, as we will show you how to fix a corrupted Word file next.

Resolving the issue: "Microsoft Office cannot open this file because some parts are missing or invalid"

Let's look at two Word document repair methods that you can try right away to recover your file and fix the error you're encountering. One of them involves updating Trust Center settings, while the other entails tweaking system configurations. Let's get started!

Method 1: Update Trust Center Settings

The most recent versions of Microsoft Word have stricter security policies for copied or downloaded files; therefore, you should update your Trust Center settings to reflect this.

Step 4: Click on “Protected View” from the drop-down menu.

5. Deselect everything and click OK to confirm your choices.

Step 6: Try restarting Microsoft Word and then opening the document again.

Assuming everything went well, you should now be able to open the file without seeing the error about “missing or invalid parts of the file.”

Method 2: Change the Component Security Settings

Another way to fix Microsoft Office errors is by modifying the Trust Center settings in its components. If your documents won't open due to your Windows security level, you need to reset the Trust Center settings to default. Follow these simple steps.

Step 1: Open the search bar, type dcomcnfg, and press Enter.

Step 2: A new window should appear. From the menu, select "Component Services."

3. Double-click the “Computers” folder in the main window.

Step 4: You should now see the "My Computer" icon. Right-click on it, and select "Properties" from the drop-down menu.

Step 5: Select the "Default Properties" option from the drop-down menu.

Step 6. Edit the Default Distributed Properties tab by selecting Defaults from the Default distributed compute communication properties drop-down.
