Automation crach on XP with latest sp and updates

Hello,

I have a class that is using Windows Automation. It works fine on newer OSs (like 7 - 8 and 8.1) but on Windows XP (using SP3 and latest updates it crashes).

The code that produces the crash is:

void CUIAutomationClient::Initialize()
{
	try
	{
		CoInitialize(NULL);
		HRESULT hr; 
		hr = CoCreateInstance(__uuidof(CUIAutomation), NULL,
                 CLSCTX_INPROC_SERVER,
                 __uuidof(IUIAutomation),
                 (void **)&g_Automation);
		if(FAILED(hr) || g_Automation==NULL) 
		{
			ret = 1;
			CoUninitialize();
		}
	}
	catch(...)
	{
	}
}

Do you have any suggestion how to fix this problem?

Thank you!
