Word Having A Problem Opening .doc file

A user was getting the following error message when she tried to open a .doc file:

Word cannot start the converter mswrd632.wpc

A bit of simple google-fu came up with the following solution:

Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Text Converters\Import\MSWord6.wpc and delete it.

Of course, backup the registry before making this change.
