I carefully followed the directions specified in http://wiki.dreamhost.com/Drupal#Drupal_5.0_Update:
-I set up a mysql database exactly as specified in step 1.
-I diligently downloaded and uncompressed the latest version of this software (v. 5.2) from the Drupal website.
-I skipped step 3, exactly as specified in the Drupal 5.0 update
-In accordance with step 4, I FTP'd the contents of the uncompressed directory to my designated location on my website. I also generated an additional directory titled /files/ and right clicked it to modify it to the setting 777.
-Having performed these steps, I then directed my browser to my site location (http://www.yes-virginia.com/Marysfamily), as specified in the Drupal 5.0 update.
-This automatically forwarded the browser to http://www.yes-virginia.com/cgi-system/install.php
-At that page I was greeted with the error message: Not Found The requested URL /cgi-system/install.php was not found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Most frustratingly, I have retried following all installation instructions three times, even having an assistant monitor my keystrokes to ensure that I am completely following all procedures. However, every time the result is the same.
Oddly, I do notice that there is a file called install.php in the top directory. However, there is no subdirectory named "cgi-system" at all.
I am pretty clueless on how to proceed. I really don't understand what's going wrong here. Any advice will be greatly appreciated.
