Joomla installation fail

[okicker]

I install Joomla with Install Central. But I obtaing the next error at the main page:
Warning: main(includes/joomla.php) [function.main]: failed to open stream: No such file or directory in /hermes/web07/bnnn/pow.mydomain/htdocs/index.php on line 26

Fatal error: main() [function.require]: Failed opening required 'includes/joomla.php' (include_path='.:/usr/local/lib/php-4.4.6/lib/php') in /hermes/web07/bnnn/pow.mydomain/htdocs/index.php on line 26

And this one in the administrator sub folder

Directory has no index file.
Browsing this site or directory without an index file is prohibited.

If you are the site's webmaster, you can remedy this problem by creating a default HTML page with one of the following names:

* index.html
* index.htm
* default.htm
* Default.htm
* home.html
* Home.chtml

NOTE: Filenames are case sensitive, i.e., Home.html is not the same as home.html

Failed opening required 'includes/joomla.php'

You can upload joomla.php in the includes directory. You can download the file from the Joomla website (http://joomlacode.org/gf/project/joomla/frs/). A manual installation is recommended, but you could probably fix what you have by uploading this file. If not, you may need to contact support to remove and/or reinstall Joomla.

Thanks, but includes/joomla.php exist, and try with your idea and put a new one joomla.php from the url that your answer, but don't work, the error change to:

Warning: main(includes/joomla.php) [function.main]: failed to open stream: No such file or directory in /hermes/web07/bnnn/pow.mydomain/htdocs/index.php on line 26

Fatal error: main() [function.require]: Failed opening required 'includes/joomla.php' (include_path='.:/usr/local/lib/php-4.4.6/lib/php') in /hermes/web07/bnnn/pow.mydomain/htdocs/index.php on line 26

THANKS IN ADVANCE for your answer!

I see this:

Warning: main(/home/users/web/bnnn/mydomain.icados/htdocs//includes/gacl.class.php) [function.main]: failed to open stream: No such file or directory in /hermes/web07/bnnn/pow.mydomain/htdocs/includes/joomla.php on line 73

Fatal error: main() [function.require]: Failed opening required '/home/users/web/bnnn/pow.mydomain/htdocs//includes/gacl.class.php' (include_path='.:/usr/local/lib/php-4.4.6/lib/php') in /hermes/web07/bnnn/pow.mydomain/htdocs/includes/joomla.php on line 73

Which may mean that you or the software entered the path and included the slash where you or it shouldn't have done so.

[YvetteKuhns]

I just spoke with support who saw the error and agreed with me. The slash IS your problem. You can uninstall and reinstall Joomla. When it asks for the root directory, simply type a single slash. You have the option of typing the full path, but you should omit the last slash after the last directory.

YvetteKuhns: Thanks a lot, your help let me find the problem
At the configuration.php, only need change the following lines:

Delete the last slash at this lines:
$mosConfig_absolute_path = '/home/users/web/b117/pow.xxxxx/htdocs';
$mosConfig_live_site = 'http://yoursite.com';

Delete the double slash between htdocs and cache (htdocs//cache)
$mosConfig_cachepath = '/home/users/web/b117/pow.xxxxxx/htdocs/cache';

Okay, I thought you might not know how to edit your php file since you used Install Central to install it. If you do, that is better yet!
