AutoIT v3 click image that acts as button

i am trying to click a button in the showmypc application (showmypc.com), called "show my pc now"

i am trying to click on a button but based off the window info from autoIT, it looks like its a picture box. i have tried using mouse click and control click with no luck. i read a few posts about using IE.au3 with image click functionality but got the impression that only works with I.E.

for mouse click i moved the window to certain x, y and used window info to get button coords. tried using mouse click with coords and did not work, no response / error.
used control click like below and still no go, no response / error


ControlClick("ShowMyPC Collaboration 3152 ","","ThunderRT6PictureBoxDC4", "left")
ControlClick("ShowMyPC Collaboration 3152 ","","[CLASS:ThunderRT6PictureBoxDC; INSTANCE:4]", "left")

here is the info from window info finder
