I currently have MS Office 2003 installed and do quite a bit of work, especially database, for a church and another non-profit organization (gratis). What I do for them must be, and stay in 2003 because they will not change their software. I am enrolled in some classes that will require 2010. The student copy is for a single computer. Will I be able to have both versions installed and use whichever is appropriate for the task at hand?

Hi
You have two options.
1. Leave 2003 installed as well as a later verison. I have tried this and have not had any isues.
2. Or you can just use, say Version 2010 and then save your documents as 2003 format.
Hope this helps.
Good luck.
Tony

I use both Office 2003 and 2010 on the same PC all the time and have had no problems. The only 'real' issue you need to be aware of is that you can only have one version of Outlook installed.

In confirm that Word 2003 and 2010 can be used together on a Windows 7 64 bit machine.
