Doing a new install of WordPress 3.4.2
When I tried to install the blog using .../blog/wp-admin/install.php
I got an error message:
The requested URL /blog/index.php was not found on this server.
Apache/2.2 Server at mysite.com Port 80
1) I deleted all the files in the folder and install again, same message.
2) I tried to change file permissions of install.php and index.php to 755, still didn't work
