XF 1.2 Error after the new installation of forum

[indicator]

I have installed the new forum in subfolder so the url would be http://www.xyz.com/forum

I am getting error when I go to http://www.xyz.com/forum/ saying page couldn’t be found without any style also.

I had vbulletin forum installed on the same directory before and it was working fine even if I used http://www.xyz.com/forum/

How can i fix it?
Thanks in advance for assistance.

What the URL to your site? Did you upload the files to /forum/?

I have installed in the root directory so everything is fine now. thanks for your assistance
