Expected behavior

I would like to start an application (based on POCO) as Windows service. This works fine, until I use required parameters.

void RRCApplication::defineOptions(OptionSet& options)
{
	ServerApplication::defineOptions(options);

	options.addOption(
		Option("cfg", "f", "Load configuration data from an XML file. E.g.: /cfg=\"C:\\RRC-M\\cfg\\app.xml\"")
		.required(true)
		.repeatable(false)
		.argument("file")
		.callback(OptionCallback<RRCApplication>(this, &RRCApplication::handleConfig)));
}

Actual behavior

When starting the service, application fails on error 78. It seems, the arguments are not passed.
I attached debugger to application when starting and size of args is 1, so no params are passed:

\poco-1.8.0.1-all\Util\src\ServerApplication.cpp, line 179:

#if defined(POCO_WIN32_UTF8) && !defined(POCO_NO_WSTRING)
		std::vector<std::string> args;
		for (DWORD i = 0; i < argc; ++i) // argc == 1 (name of executable)
		{
			std::string arg;
			Poco::UnicodeConverter::toUTF8(argv[i], arg);
			args.push_back(arg);
		}
		app.init(args);
#else

I have registered the service as

sc create MySVC binpath= "C:\MySVC\MySVC.exe /cfg=\"C:\MySVC\cfg\app.xml\"" displayname= "MySVC" start= auto

In properties of the service (in Windows service list using mmc), I can see the path:
C:\MySVC\MySVC.exe /cfg="C:\MySVC\cfg\app.xml"

However, the parameter cfg is obviously not passed. When starting application from command line, everything is OK.
The question is, how to pass params using service?
Thank you!
