Download the Windows Install clean-up utility from the Microsoft site, Install it, run it and select the Norton 2008 product and un install it. Reboot, then try your installation again. Let me know if this works, I have other suggestions if this does not work for you.

Yes it is possible.
To install full version you need either to purchase a disk or to purchase the download from Symantech.

If you have purchased the download or if you want to install the trial version download, just copy the install file onto an usb memory stick.

Plug the memory stick with norton install file onto your computer with no internet and run the installer from usb stick.

This will install norton with no need for the Internet.

If you buy nortom full version you may need to validate installation by phone, but that is not complicate.

You can download Norton from one of the websites below:

Norton AntiVirus for Windows 2000/XP/Vista

Norton AntiVirus 2009 - Free software downloads

uninstall the older version through add/remove programs http://spftrl.digitalriver.com/pub/symantec/tbyb/NAM/N360S300EN.exe
use this link and download and install the latest version
