If you want to run in ISAPI mode on IIS 6 you probably want to keep this in mind: http://bugs.php.net/bug.php?id=37483 It will depend on the extensions you're running and how you configured IIS but I think you should be fine by just stopping the World Wide Web Publishing service, overwriting your files (probably be a good idea to make a backup copy first), and then restarting W3SVC. -zeb -----Original Message----- From: Simon Renshaw [mailto:simon@xxxxxxxxxxxxxx] Sent: Friday, June 16, 2006 2:29 PM To: php-windows@xxxxxxxxxxxxx Subject: Upgrading from 5.0.5 to 5.1.4 Hi, I'm currently running version 5.0.5 on Windows 2003. I'd like to upgrade to 5.1.4. To do so, I just need to unzip 5.1.4 zip in my PHP dir and overwrite everything? Thanks!
