Zeeshan Butt The post description din't refer any thing to ThingWorx Studio. And I see that you've reported "Composer for windows" - Composer is again ThingWorx Platform (and not ThingWorx Studio), did you mean installing ThingWorx Platform (Composer) or installing ThingWorx Studio??
Assuming it is ThingWorx Studio, do you see the studio installer logs in <USERHOME>/appData/Roaming/ThingWorx Studio location? If so, can you please the logs.
