Can't work with specific window

Hi! First post on AutoIT Forum! I am facing a big problem. I have tried commands like WinMove, ControlClick, MouseClick and many others with success, interacting with Calculator window. Now I am trying to click o a button of HWiNFO32 program but i just can't. No ControlClick, no WinMove no MouseClick, not even Send command!!! What can I do? Is there a workaround? You can try it for yourself, try getting HWiNFO32 portable and then click on something or move the window. I can't. Where's the problem?
