please consider this option.
uninstall your old office 2007 and install office 2010

i highly recommended that option.

Make sure Office is properly installed.
Once it is, double-clicking on any Word document should open it right away.
If it's not, I suggest you visit Microsoft's Support website here : http://support.microsoft.com/gp/gp_off_main
Hope this helped.

You probably were using the trial version of the software. You have to buy Office 2007 to get a Product Key.
The Product key or serial key is the license you receive when you purchase Office 2007 or any Microsoft software.

Best thing to get is Open Office, which is fully compatible with Office 2007 or any ms office, and you do not have to spend dollars because it is free. Download it from this link:

Unfortunately MS-Office 2007 is not legally available for download.
You can use Open Office(http://www.filehippo.com/download_openoffice/) instead. It the best available word processor free.

Type in the product key. This can be found on the package when you purchased Microsoft Office 2007.

Outlook 2007 is stricter than 2003 about SMTP authentication. It could be the case that 2003 tried automatically to connect without authentication when authentication failed, while 2007 throws an error.

Please verify the settings for authentication in your account, and uncheck the box “My outgoing server (SMTP) requires authentication", on the "Outgoing Server" tab.

try to re-install the software.
