Fresh Install on new hard drive with Windows 7 install

My hard drive has been going downhill and I have decided to replace it with a brand new drive that I just installed. Presently, it is downloading all of the Windows 7 updates. I used my Windows 7 full license DVD to install Win7 and so far that is where I am at. I have not yet installed anything else, including drivers.

I want to get my Comodo CIS Complete license back up and running asap, before I get too far into having to download anything further. How do I get my CIS license active on this replacement drive?

Thanks

Do you still have the license key? Then I would think all you need to do is fill in the license key after having installed CIS Complete.
