Installation Error

I don’t know much about PHP programming but after loading all the files and accessing the install.php, I am getting the following error, no matter how hard I tried to resolve it…

Warning: require(/home/mendatin/public_html/herantiagingsecrets/blog/wp-includes/cache.php) [function.require]: failed to open stream: No such file or directory in /home/mendatin/public_html/herantiagingsecrets/blog/wp-settings.php on line 128

Fatal error: require() [function.require]: Failed opening required ‘/home/mendatin/public_html/herantiagingsecrets/blog/wp-includes/cache.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/mendatin/public_html/herantiagingsecrets/blog/wp-settings.php on line 128

I am looking forward for some help…
