Q: I have Microsoft Office 2007, and am installing Office 2003. If I install Office 2003 will it delete 2007 and keep 2003 or will an error message come up? Can I keep both? eww......? oh........ I have Word 2007, Outlook Express 2007, and all those others, and now I'm getting Word 2003, Outlook 2003, and all those others lol dang Jane your good Thanks Mr. C too :) omg everything went wrong! Outlook wont work now, word looks ugly, and now I got no email :( its all ruined. I'm going to try to install Outlook Express again along with everything else. I'm going to try to install it all again :) This time I will try to install Microsoft Office Word 2003 without Microsoft Office 2007 being installed on my computer! I think I might chose Jane as BA Oh, but don't feel bad Mr. C you did good too when you answered my question, I wish I could give you all 10 points! I like this feature :) oh, just to let you all know, I'm running Windows Vista Home Premium but it has the Windows XP Style theme which is blue. And I tried downloading Virtual PC but I couldn't because it does not support Windows Vista Home Premium :(
A: Yes, you can have both Microsoft Office 2003 and Microsoft Office 2007 on the same computer by using virtualisation. Ensure you have the licences to run both (and the virtual OS). If you just install Microsoft Office 2003 over Microsoft Office 2007, you'll just get 2003 - the two can't run "together".
