Fixing Corrupted Word Documents
Over time, it is possible that a Word document becomes corrupted. While you still may be able to work normally with the document in Microsoft Word, it is possible that Help Producer cannot convert the document properly because certain internal functions of Microsoft Word fail due to errors in the document.
Use a different file format
Due to its complexity, the binary file format of Microsoft Word (.doc files) is prone to errors. If technically possible, you should save the document using a different file format, such as XML or RTF. If you are using Microsoft Word 2003 or higher, we recommend saving your document using the XML file format.
Repairing documents (Word 2002 and higher)
Starting with Microsoft Office 2002, Word allows you to ‘repair’ a document. This option performs a more extensive consistency check of the document, and can correct certain problems.
