When installing Drupal 7.31 in the first page, I can't install with the following error message.

An AJAX HTTP error occurred,HTTP Result code 2: debugging information follow, Path:htp://localhost/install.php?
profile_standard&locale-en&op_do statustext: Unknown ResponseText:

error page show : Fatal error:call to undefined function node_types_rebuild() in C:/APM_setup/htdoc/includes/common.inc on line 7512

line 7511---entity_info_cache_clear(); 7512---node_types_rebuild(); 7513---//node_menu() defines menu items based on node types so it needs to come 7514---//after node types are rebuilt. 7515---menu_rebuild();

Every time i delete and again try to install this always it's same.

    Are you sure you've downloaded all sources? It seems there are files missing. Is the file modules/node/node.module present?

I had problem like this. You need to increase memory_limit.

For XAMPP: you can change it globaly in php.ini (in xampp located in '\xampp\php\php.ini')

memory_limit = 8M // search for this "memory_limit" and adjust it by your needs (min 64M)

For WAMP: right click on the WAMP icon, then navigating to the PHP folder/menu-thingy and selecting php.ini, and find memory_limit (like on XAMPP)

After you made a change restart Apache and try to install Drupal from the beginning.
