If you wish to open a Microsoft Works document in Microsoft Word and don't have a copy of Works installed on your computer, it is still possible to convert the document to a format that Word can open. You will simply need to download an addon known as the Works 6-9 Converter for Microsoft Word from Microsoft which will allow Word to convert the document itself.
Download the addon from the following location: http://www.microsoft.com/downloads/details.aspx?FamilyId=bf41401e-70fa-465d-ae2e-cf44dbf05297&displayLang=en
Once you have downloaded the addon, close Word if you have it running and double-click the addon to run it. You will be asked to accept the Microsoft licensing agreement for the addon, and then will be given the option to install it. Click the "Install" button and wait while the installer finishes.
Open Word once again when the addon has finished installing. Click the "File" option in the menu bar if you are using Word 2003, click the Office button if you are using Word 2007, or click the "File" tab if you are using Word 2010. Select "Open...", then change the "Files of Type" option in the "Open..." dialog box to "All Files." Locate the Microsoft Works document and double-click it; Word will automatically convert it to a format that it can use, and you can save it as a Microsoft Word document when you have finished using it.
