Setting up Zend Debugger

I try to configure zend debugger to debug php pages on my local apache server. I followed all instructions from the official forum (http://forums.zend.com/viewtopic.php?f=59&t=962#p4313) but开发者_如何学运维 I fail to see the Zend Debugger listed by phpinfo(), after I restart Apache. My php ini is this:

zend_extension_ts="C:\Program Files (x86)\PHP\Zend\php-5.3.2\5_3_x_nts_comp\ZendDebugger.dll"
zend_debugger.allow_hosts=192.168.0.104/32,127.0.0.1/32
zend_debugger.expose_remotely=always

The path to ZendDebugger.dll is correct. I'm using windows 7, 64 bit. There arent any error messages in the apache log or in windows application log.

Are you using Thread-Safe version of PHP. Check Zend Extension Build, PHP Extension Build in php info file. If you are using Thread-safe version, you cannot use Non-Thread-Safe version of ZendDebugger.dll. Currently no ZendDebugger.dll is out there for threadsafe PHP 5.3.0.
