I have to write a document that will be later opened by other people in Word 2003. The document contains lots of equations and AFAIK Word 2013 doesn't use the same equation format as Word 2003 so they will be converted to images when I save in the old .doc format.
Where can I download a trial version of Microsoft Word 2003?
I found a link to Standard Edition here but it requires you to enter a registration key during installation (which I obviously don't have).
I need to write equations specifically with Microsoft Equation 2.0 or 3.0 (it's their requirement) and LibreOffice uses another format as well as MS Office 2010/2013. I couldn't find a way other than using MS Word 2003 (please tell one if you know).
OK, it seems I finally found how to insert Microsoft Equation 3.0 equations (Insert -> Object -> Microsoft Equation 3.0).
