What happens to Microsoft office 2000, if I download Microsoft office 2007 onto my computer? I recently purchased the Microsoft Office 2007 for my home PC but I'm thinking about downloading it to my work PC since we're still using 2000. But I'm afraid of what would happen if I add the 2007... Will it delete or over ride the 2000 version? If so, is there a way I can download it without that happening?
