application working in one but not in another machine

var x = new ActiveXObject("AxControls.HelloWorld"); 
working fine on my machine and x gives object but same thing I did on another machine then getting error Automation server can't create object,  I did browser setting same for both still not working.
I need to check why its working on my machine and not for another. Both machine have same version of visual studio every thing is same.
How can I check where my component register and how can I do for other.
