That ain't helping him much...Upload the files to your webhost. Asit uploads get a database ready...Once it has uploaded CHMOD all files to 755 or 777. Go yo your brow and go to www.yourdomain.com/forum/install/index.php
Hrm v1.3.1 is available on fantastico! Its alot easyer to set up as fantasico sets everything up for you! Of look in the documentaions folder and read the read me file which will help you install IPB!
fantastico took it off because Invision Power wont put the IPB 1.3 download link up, its still legal to use the free version of IPB 2.0 and 1.x but you cant give it out, only cpanel has it pre-installed i believe. Go under addons or something like that and it should have it...
