I'm having problems getting COM objects to work. I'm trying to get Crystal Reports to work with my PHP application and have been working on this for the past 2 days. I've done so many searches and have tried every example I have come across. I always get HTTP 500 server errors with PHP Fatal errors in the log files when trying to load COM objects.
I have PHP 5.2.6 installed on two different Windows 2003 servers, one with IIS 6 and the other with Apache HTTP 2.2 server. PHP works great on both servers, but when I try to create a new com object, I get an HTTP 500 error. Below is some of the code that I have tried with no success.

$creport=new com("CrystalReports12.ObjectFactory.1 ") or die("cannot load cr com");
$o_CrApplication = $creport ->CreateObject("CrystalDesignRunTime.Application");
or
$o_CrApplication = $creport ->CreateObject("CrystalRunTime.Application");
or
$o_CrApplication = $creport ->CreateObject("CrystalRunTime.Application.12");
I have tried other com objects and get the same HTTP 500 error.
$fso = new COM("Scripting.FileSystemObject");
$f = $fso->GetFile("c:\\test.txt");

I checked my php.ini and made changes to the [com] section, but still have problems.
[COM]
com.allow_dcom = true
com.autoregister_typelib = true
From the command prompt, I run php -r "new COM('CrystalReports12.ObjectFactory.1')-> CreateObject('CrystalRuntime.Application.12');" and do not get any errors or warnings. 
I currently have Crystal Reports 12 installed and even tried to test with version 9, but always get the HTTP 500 error with log errors such as the following:
PHP Fatal error:  Uncaught exception 'com_exception' with message '<b>Source:</b> Unknown<br/><b>Description:</b> Unknown'
PHP Fatal error:  Call to undefined method com::OpenReport()
PHP Fatal error:  Uncaught exception 'com_exception' with message 'Failed to create COM object


I need to get this to work and can't seem to find the solution. Let me know if you need me to provide any additional information.

Thanks,
Dave
