Reinstalling CIS after reformatting windows

In about a month’s time I will have to reformat. I noticed in CIS I saw a serial number issued to me (I’m using the free version). After I reformatting will I still need that serial number when I reinstall CIS? Or can I just install it like usual without any problems?

Hey, Um - To be honest… I’m not quite sure! I’ve reinstalled comodo alot of times And have never taken any notice of the serial numbers.

It shouldn’t be a problem, I think it’s some form of identification that comodo may use in the near future for threatcast. (My guess)

Hope this hekos.
