Load fails

[jbattin]

I am running Win 7 with Apache 2.2. My phpinfo says I'm running PHP 5.3. I downloaded ZendGuardLoader-php-5.3-Windows.zip and extracted.

I added these statements to my php.ini:
zend_extension=D:\Websites\Zend53\ZendLoader.dll
zend_loader.enable=1
zend_loader.disable_licensing=0

I get an error stating: Failed loading D:\Websites\Zend53\ZendLoader.dll

It doesn't matter where I put this file or if I use / instead of \, the file will not load.
If I use version 3.3.3 I get this error:
Zend Optimizer requires Zend Engine API version 220060519.
The Zend Engine API version 220090626 which is installed, is newer.

I can't figure out how I could change the API version anyway.

Can someone help me shed some light on this?

Thanks for the help.

the most likely problem is you are running TS PHP and Guard Loader requires a NTS PHP build.

I'm sorry for my stupidity - but what is TS Php and NTS Php? I have the standard PHP 5.3 installed.

Thanks.

There are "Thread Safe" (TS) and "Non-Thread Safe" (NTS) builds available at PHP.net (http://windows.php.net/download/). You need a NTS build for Guard to work. BTW NTS builds are recommended by both MS and Zend as better and more reliable.
