After installing the Office2007 Compatibility Pack, office2003 Open or unable to open some docx, prompt to open the file error, determine the content is blank. It is possible that this docx file has been added in a higher version of Office, causing the compatibility pack to fail to resolve.
In general, Word documents created in Word2010 cannot be opened and edited in Word2003 because Word2003 cannot recognize Word2010 files with the. docx extension, and Word2003 can only open doc files.
If the office2003 installed Compatibility Pack is still not open docx, you can download wps2012 personal version try, I just downloaded wps2012 can open office2003 file, and then save as doc file, So the offic2003 can also be opened.
