Multiple licences/keys

I’m trying out Comodo Firewall, and it looks very promising so far. However, I’d like to clarify something about the licence/keys. I have four PCs I might install Comodo on; do I need to get four keys or can I use the same key? If I need four keys, do I need four e-mail addresses?(!) Or can I just make multiple requests?


Each license can be collected a maximum of 4 times.

But, you can apply again using the same email address, so order away… :SMLR


Thanks for the quick response - that policy sounds pretty reasonable.
