To a lesser extent open Office can export PDFs & you can -- like I did with the older versions -- print them to Adobe Distiller as well.
I had Office 97 & Open Officve in my older 'puter at the same time (Windows 2000 Pro) As i mostly see it & they didnt interfere with each other. As you know (Just remember to disaable or do not use file association for .docs etc. at the last stages of installation, so you won't hose up Word etc)
Open Office can also read .doc files (ditto for Excel etc) and
I found it (personally) better than Word (die, paperclip, die, why the painfully fuck you won't die?) and less financially grating experience. As yet yMMV, etc.
Anyway, if you intermittently need any help with critically tinkering with my sheets, let me know and I'll see what I can do for you.
