Unpack www package [rar/zip/exe] to the top dir [\] of a drive [ex: C:  E:\], forming \www\\...
  
  Edit C:\www\my.ini, to reflect the correct drive letter under the following fields...
  
  Under "[client]" and "[mysqld]" sections...
  
  socket = C:/www/tmp/mysql.sock
  
  Under "[mysqld]" section...
  
  basedir = C:/www/mysql5/
  
  datadir = C:/www/mysql5/data/
  
  Edit C:\www\php.ini, to reflect the correct drive letter under the following fields...
  
  include_path = ".;C:/www/webroot/;C:/www/php5/includes/"
  
  doc_root = C:/www/webroot/
  
  extension_dir = C:/www/php5/ext/
  
  session.save_path = C:/www/tmp/
  
  Copy my.ini and php.ini to your \%SystemRoot% (Win2000 -> C:\WINNT, WinXP -> C:\WINDOWS) directory.
  
  Delete file libmysql.dll, if present, from your \%SystemRoot% (Win2000 -> C:\WINNT, WinXP -> C:\WINDOWS) directory. [note that this is not needed for the majority but will help the few that have had PHP dll load problems]
  
  Go to 'Start' » 'Settings' » 'Control Panel'; Select 'System' - 'Advanced' - 'Environment Variables...'; Under 'System variables' select 'Path'...
  
  Add to Path..
  [note that the individual locations are separated with a ";" and that you will need to place a ";" at the end of the original PATH, to separate it from the first appended location.
  
  C:\www\openssl\bin;C:\www\Apache22\bin;C:\www\php5;
  C:\www\mysql5\bin;C:\www\perl\bin;C:\www\tomcat5\bin
  
  Reboot your system. This is necessary for Apache to be able to load mod_perl and for PHP to contain the updated PATH. The PATH variable will not be fully (system-wide) updated until a system reboot.
