Error: PHP is not runningWHAT??? The PHP test file worked perfectly fine! I googled and googled some more trying to find a solution to this and while there question appeared frequently, there was never a good answer. I finally figured it out myself though!
WordPress requires that your web server is running PHP. Your server does not have PHP installed, or PHP is turned off.
The problem was in how I was accessing install.php. Through Windows Explorer, I had navigated to my WordPress directory and double clicked on readme.html. The file opened in Firefox. Then I clicked the hyperlink in Step 2 "wp-admin/install.php". This opened the file with the error, and here's the problem: look at the address bar:
file:///C:/apache/htdocs/wordpress/wp-admin/install.phpIn order to make it work, you need to hit it from LOCALHOST
OS: Windows XP SP3
Webserver: Apache 2.2
