My father's Acer laptop is on Windows 7 Home-premium 64-bit, it detects the bluetooth dongle, then I try to connect my father's phone and the laptop, it detects the phone but can't install any drivers accept 1 or 2 drivers. Then I can see the phone's folder in Windows Explorer then I double click it , then it says the "Windows Explorer has stopped working" error code, what should I do?
