Word 2013 and 2003 installed; default programs won't recognize 2003

[Weboh]

I have Word 2003 and 2013 installed on my computer. Word 2013 can't edit files with custom XML elements, so I want to use 2003 to open them. However, whenever I double-click an XML file, it launches 2013. I tried to fix this by selecting "open with" and browsing for Word 2003. But whenever I do that, the program that appears in the open with dialog box is Word 2013--not 2003. I can't select Word 2003 from any open with dialog box from anywhere because of this. How do I fix this?

It's actually best recommended not to have 2 versions of MS office at the same time, but I guess yours is a special case.

Try opening Word 2003 and open your document from there. See if it works.

It does work from there, but I want to be able to open them directly from their directory.

The order of Office installation on your computer seems to be important. These MS websites may help you.
