I tried installing it but it says antivirus software wont allow it to open. I know nothing of computers does anyone have any ideas on how to disable the firewall it mentions. Thx in advance

You will have to deactivate your anti-virus software in order to install the Co8 modpack.

If you don't know anything about computers, you should probably find someone who knows about computers who can install it for you. Messing around with your firewall can really put your computer at risk if you don't know what your doing.

There is lots of info in the sticky thread on how to install the Co8 modpack, once you find someone who knows what they are doing.
