Like 将軍 Kirisute Gomen said, once you get all the files uploaded point your browser toward the install.php file (which should be in a seperate file called 'install' from the main dir).
That should get you started at least, and once you are required to create a MySQL database it will tell you. CPanel has a wizward for setting one up, so it should go pretty easy for you. If you need any further help, my msn in in my profile ~wink~
Hi thanks for the info i have now set it up it wasnt installing because 1 file wouldnt upload but i got there in the end. And the Mysql database was alright to set up.
I always unpack the phpBB package and just upload all the files in a zip and just extract the zip in File Manager in cpanel (thats the quick way of doing it) -8)-
