I Can not install apk files on device or emulator in ADT-15.0.0?

Question

I was developing my app and everything was OK. I installed ADT - 15.0.0 and installer_r15-windows.exe. After that, when I press Ctrl+F11 my project is uploaded but stayed in installing state without any progress. Why? can anybody help me?

thanks,
