Can Office 2007 Be INstalled on Computer Running Office 2003?

[NewW7User]

I use Excel & Outlook 2003. But I am constrained by the 256 column limitation on Excel 2003. Can I install Office 2007 so I could use Excel 2007 while Office/Excel 2003 is running on the computer?

There are used Office 2007 copies with product keys available on ebay.

You could try.

One of my Windows 7 PC runs Office97, Office2007/2010. three Office copies same time. no conflicts.

Thank you for your experience information.

Definitely yes, you can install multiple versiones of Office side-by-side and they'll run normally.

The only potential point of conflict will be file associations, the last installed version will "steal" associations from the former. You can of course fix those manually afterwards.
