The Microsoft Works 6-9 converter allows Microsoft Word users to open, save, edit Microsoft Works (.wps) files. Previously, when you installed the converter on Windows 7 and tried to open the file in Word, it would say that the converter needs upgraded and wouldn’t work. If you “upgraded” the same thing would happen, in a loop. Well it seems that Microsoft finally fixed the Converter so that it opens .wps file in Word without giving the error.
