This isn't a problem. Actually, nobody has the right to order you to use Microsoft Office - it's overpriced, bloated, and unnecessary.
Take a look at this file http://files.getdropbox.com/u/446031/pdf-firefox.jpg - made with Open Office, exported to PDF format and you can open it in
Firefox (The actual file is here - http://files.getdropbox.com/u/446031/Term%201%20ENGLISH%20test1%20-edit.pdf - in my dropbox What about that font? - that's AEZ Kate's handwriting) - now this won't open in Word and display that font will it? That means if anyone else tries to print a .doc or .docx file then the font will be substituted - it won't be right.
I use Open Office - and I keep an .odt file for my own use, and when I send documents to other people, I hit the 'pdf' button - to export it as PDF.
PDF is actually a 'portable document format'. Once you export a file as PDF, it's pretty fixed - nobody can mess it up, or edit it by mistake - and it looks and prints exactly the way you want it to (don't believe me? just open a .doc or .docx file on a few machines - and print on three different printers!!! Never twice the same document...)
The answer is indeed to use Open Office. It will open .doc files, and can save them as PDF for export, or for .odt (or just leave them as .doc or .docx)
You can get a portable edition of Open Office, so that you have your software on a USB - which will work on ANY windows computer (portable means it runs from a folder on your computer, or on your USB - to 'install' you can drag a copy of the folder to the hard drive of a computer. It's legal and free to install Open Office without paying - to every machine in the land!!!
Now tell me you need Microsoft for ... compatibility??? What a joke!
Compatibility is the opposite of Microsoft's business plan.

If you want a local install, then go over to http://www.openoffice.org - keep the installer on your USB if you like, but portable works so much better - say NO to .doc or .docx format. It's wrong.
.odt is so very much smaller than .docx and it works so very much better - and PDF is universal, I can open it in my old Nokia N70 - and it looks fine (exactly like the computer)
