My laptop came with a 60-day subscription to NIS 2012 and it just expired 4 days ago. I have been using AVG for the time being but I have remembered I have a copy of NIS 2009 lying around that I bought a while back. I decided to install that to save money but the installer won't start since it's not compatible with Windows 7.
A quick Google search informed me that updates have been released to make NIS 2009 and Win 7 compatible, but I am not sure if I can apply them since the program isn't originally installed. Is there any way around this, having both the original copy on CD and the update? Any suggestions?
