I’m looking at placing comodo free firewall in a lab of 10-15 computers, however they are already built and running. Should I request OEM Info, try to use my one registered key on all the computers, or try to register for multiple licenses?
G’day and welcome to the forums.
If you download the latest release version (2.4.18.184) it is self activating and no longer requires an activation code.
There is no need for an OEM license - CFP is totally free for both private and non-commercial use. I’ve currently got it installed on over120 PCs.
The more the merrier.
