Hi all.
I have a question, I hope you can help me clear things up.
I have purchased 6 New PCs without any MS Office software. I would like to buy 6 licenses for MS Office Professional 2007 but I would like to run Office 2003 for the time being. So what I am asking is:

• Can I buy Office Pro 2007 Licenses and use these licenses to run Office Pro 2003?
• If this is possible, can I use existing media (i.e. an existing copy of 2003) to install the software but use my new license numbers?
• When the time comes to change over to 2007, can I just uninstall 2003 and reinstall 2007 using the same license numbers?

I have had a look at some older threads but I am not 100% so I thought I would dive right in and ask.
Thanks for your help in advance.
Simon

Downgrade rights are only available for Volume Licensing versions of Office.

You will have to have the media for 2003 in order to install it and will need a product key for 2003. If you have volume licensing this can be provided for you through your licensing partner.
