Hi, I'm in a similar boat. Did you get any joy from any other sites?, as obviously nobody replied here. With my new computer I have a 60 day or 25 goes free trial of Microsoft Office 2007. In honesty I need only the basics so 'Open Office' probably is ok for me and I don't want to spend any more on MS software. However, I'm not sure what happens after my trial expires with say EMails containing attachments raised on MS Office programs - right now a Powerpoint attachment for example automatically tries to open with MS Office and I get the message saying I have a further say 20 free goes using the free software without inputting a licence key code. When I've used up all my free goes how do I make the attachment open automatically with Open Office? I also have an option to upgrade to windows 7 if I want but from what I've read so far that'll probably just give me more probs not less.
