Repair Word (Office)
Word can detect and repair problems associated with Setup. This feature uses the Windows Installer to correct problems with missing files and to repair registry settings.
You can use the following three methods to repair or to reset Word files and values:
- Method 1: Use the "Detect and Repair" feature
- Method 2: Repair Word in Maintenance Mode Setup
- Method 3: Reinstall Word (Office)
Note This method is the least aggressive mode of repair. If this method does not resolve the problem, you may still have to use one of the other methods.
To run the Detect and Repair feature in Word 2003 and in earlier versions of Word, click Detect and Repair on the Help menu in Word. The Detect and Repair feature fixes and repairs Word. All files, registry entries, and optional
shortcuts for all Office programs are verified and repaired. If you run Detect and Repair from Word, all other Office programs are also checked. This feature performs only a checksum.
The Detect and Repair feature can also restore the Word program shortcuts on the Start menu. To restore the Word program shortcuts, click Help, click Detect and Repair, and then click to select the Restore
my shortcuts while repairing check box.
If Detect and Repair does not correct the problem, you may have to reinstall Word. The Reinstallfeature in the Maintenance Mode dialog box performs the same action as Detect and Repair, except that Reinstall copies
a file when the files are of equal versions. Detect and Repair does not copy over the file when the installation file has the correct version and checksum.
Note The Detect and Repair feature does not repair damaged documents or damaged data keys in the registry or in the Normal template.
If a file that Word uses at Startup is missing, the Windows Installer automatically installs that file before it starts the program.
In Word 2007, run the Microsoft Office Diagnostics feature. To do this, click the Microsoft Office Button, click Word Options, click Resources, and then click Diagnose.
In Word 2010, repair Word or the installed Office suite in Control Panel.
