Find a way to know if the oleacc.dll is working as expected or not

Hi All,

I have an application that will use oleacc.dll to grab the other running windows application text.

Basically, I have used these two functions of oleacc.dll

AccessibleObjectFromWindow

AccessibleChildren

If I delete a registry entry (eg. HKLM\SOFTWARE\Classes\Wow6432Node\TypeLib\{1EA4DBF0-3C3B-11CF-810C-00AA00389B71})  related to Oleacc.dll then these functions work without throwing exception but not giving the expected result. And the end result is the application is running but not doing the expected work.

So, I wanted to know if there is any way to find if the oleacc.dll (Microsoft accessibility) is working as expected or not. 

Thanks

Prakash
