Hope this will be musch of help
Word 2007 should have no problems opening .doc files – it is usually the other way around (older versions of Word cannot open .docx files without a converter). You can easily save your documents as .doc files instead of .docx by using the “save as” feature, which makes your documents easy to open regardless of which Office software you are using. Hope this helps.
