I am having the same problem installing on personal pc.
Running:
OS: vista
xampp v.win32-1.7.4 with Apache and mySql running.
wp v. 3.2.1
When I type:
https://localhost/mywebsite/wordpress/wp-admin/install.php
I get the following error message:
“Fatal error: Call to undefined function __() in C:\xampp\htdocs\northpolebookworm\wordpress\wp-admin\includes\file.php on line 11”
file.php line # 11 reads:
“‘index.php’ => __( ‘Main Index Template’ ),”
xampp is in c:\xampp
website is c:\xampp\htdocs\”mywebsite”(without quotes)
wp-config.php is in c:\xampp\htdocs\mywebsite\
wp is in c:\xampp\htdocs\mywebsite\htdocs
file.php is in c:\xampp\htdocs\mywebsite\htdocs\wordpress\wp-admin\includes\
