Running app in Android Studio

问题

I have an Asus Zenfone 2 Laser and I'm using android studio to create apps. When I load an application stored in the hard disk of my computer for debugging, no problems, but when the application is stored in a USB device, at first android studio warns that there is already a version of the same app in my phone and asks if it has to uninstall it in order to install the new version; when I click the button to uninstall it, it doesn't install the new one...

How can I fix the problem? Thanks
