ControlClick highlights but do not click

[DJ_TLG]

Hello everyone,

I am a new user of the AutoIt. I come from Java backgroung. I am trying to automate an installer using AutoIt.

My problem is I am trying to using ControlClick on the next button of the installer and I think it is able to target it and send command to it but it is not clicking to it. When I run the 

ControlClick("PTC",'','[CLASS:TkChild; INSTANCE:4]')

or

ControlClick("PTC",'','[CLASS:TkChild; INSTANCE:4]')

commands the button gets highlighted(light blue color, same as my mouse is hovering on it) but it doesn't get clicked. 

I also tried to get the handle of the button but i think I am not able to get it because i get 0 from the following command.

ControlGetHandle('','','[CLASS:TkChild; INSTANCE:4]')

Please help. I don't know if I am doing something wrong or my installer is being uncooperative. Also let me know if there is any alternative if you think this will not work.
