Upgrade to Windows 7 has deleted NIS2009 and now I can not reinstall it using the CD or backup files

Hello,

 

I recently completed a clean install of Vista and during that process all of the NIS2009 folders were removed which was expected and did not really bother me as I have my NIS2009 installation CD and ran a system backup. Several days later (and many headaches on) I installed the 32bit Windows 7 Ultimate system. It was installed as a new installation rather than upgrade. The installation was a sucess and I was able to retrieve all of my files from my backup however, I haven't been able to reinstall NIS2009. When I insert the NIS2009 CD I get the message "This product requires Windows XP or Windows Vista". I understand there is a Windows 7 upgrade available for current Norton account holders but I can't use it as no Norton software can be detected on my computer. How do I reinstall the NIS2009 onto my Windows 7 system? I seem to have all of my Norton folders from my Vista system backup but I don't know which or even if any of the files can be used to reinstall the NIS2009 program? Sorry for my vague message....as you can probably tell, I'm not really up to speed with all of this. I would really appreciated your thoughts on this. 

 

Cheers!
