I just got this phone yesterday and I am having a huge problem installing apps. When I download them them come in many different files and include a setup file, when I open the setup it opens up a webpage which I don't know what to do with. Can anyone help me out with installing these apps to my device (htc-6800)? All I really want to install is an app that closes programs instead of minimizing them. Thanks!
