I am quiet facing a bit issue with my OS. I am using Windows 7 here. And I thought to explore more about windows registry. So here I am having a bit issue with windows installer. I am trying to find settings related to that so that I can deny user access to the same. Here whenever I am trying to install anything it keeps on crashing. I am not able to figure out why this happens. Sometime when I go ahead with new game setup that is also crashing. Major issue lies with Windows installer and I am unable to find fix for that.
