That is how Microsoft says to do it also. But if you scroll down to "Repair Word (Office)" there are other methods. support.microsoft.com/kb/822005
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)
Method 1: Use the "Detect and Repair" or "Microsoft Office
Diagnostics" feature 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 Reinstall feature 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.
Method 2: Repair Word in Maintenance Mode setup Note This method is a
moderate mode of repair. If this method does not resolve the problem,
you may still have to reinstall Word.
The Maintenance Mode Setup process is similar to the process found in
earlier versions of Word. The Maintenance Mode Setup process allows
you to repair, add or remove features, and remove the program.
