I'm trying to install Zorba on a Windows 7 machine with the help of these instructions. I've completed the "Verify Zorba" section ok, but I can't complete the section "Enable Zorba extension in PHP". When I attempt to restart PHP, a Windows dialog box pops up saying;

Do I need to compile from source? The instructions say to compile Zorba from source but instead have downloaded the Windows installation package from the Zorba download page. Do I also have to compile from source? Surely not?

Missing zorba_api_wrapper.php The instructions say "locate the file zorba_api_wrapper.php" but I can't find a file of that name. There is a file called zorba_api.php so I've used that instead. Is that the correct file?

php-cgi.exe I'm running the CGI version of PHP. I start it from the command prompt by doing;

php-cgi -b 127.0.0.1:9000

Could that be what's causing the error dialog? I guess it's more common to have Apache start PHP. (I'm using Nginx not Apache.)

Update

As suggested by Rodolfo, I've added C:\Program Files\Zorba XQuery Processor 2.0.2\bin to the PATH environment variable and uninstalled an older version of Zorba. Now when I try to start PHP by doing;

php-cgi -b 127.0.0.1:9000

I get a different Windows dialog;

If I remove the line extension=zorba_api.dll from php.ini, PHP starts ok.

>>Do I need to compile from source?
Windows Installation Package is fine, this should work.
>>Missing zorba_api_wrapper.php
This is included along with zorba_api.dll in [ZORBA_INSTALL_DIR]\share\php

The error could be caused by two reasons:
a) zorba_api.dll is not able to locate zorba_simplestore.dll. Make sure your zorba_api.dll is able to reach zorba_simplestore.dll, the easy way is through PATH environment variable.
b) you have an older zorba_api.dll not related to a newer zorba_simplestore.dll. Make sure you don't have an older version of zorba colliding with your current version.
