I haven't installed anything since I can't view the installation page. All I did was place the phpbb2 folder that I downloaded from this site, and all its contents into my website folder on my server. It is located on my server. The server is part of my network, and is hosted locally. Not my actual computer, but my network.
From what I read in one of the viewable pages in the phpbb2 folder is that the next step is to go to the install page at mywebsite/phpBB2/install/install.php. The problem is that this page isn't viewable.
