I have the same error. I'm trying to start a new php process to run a php script in the background. This is what i'm doing:

$WshShell = new COM("WScript.Shell");
$oExec = $WshShell->Run('C:\php\php.exe startEngine.php'); 

the script runs ok when i start it from a command window.
but it gives me this error when i try to run it from a php page:

Fatal error: Uncaught exception 'com_exception' with message '<b>Source:</b> Unknown<br/><b>Description:</b> Unknown' in c:\Inetpub\wwwroot\M3PHP\Engine\EngineService.php:60 Stack trace: #0 c:\Inetpub\wwwroot\M3PHP\Engine\EngineService.php(60): com->Run('C:\php\php.exe ...') #1 {main} thrown in c:\Inetpub\wwwroot\M3PHP\Engine\EngineService.php on line 60

Has there any progress, or workaround with this problem ?

I've just tried it with Apache/2.2.4 (Win32) PHP/5.2.3 on a Windows 2003R2 server. The same was orrucing with PHP v5.2.2.

I tried on Windows Vista SP1, PHP 5.2.1 and getting the same error.

Are there any news about this?

Hello guys,
I've had similar problems trying to start application in the background, but 
always getting the Source: Unknown error.

For me the cause was, that backslashes weren't escaped, so please double check 
your code.
