These are the excertps I got from the site http://www.topnotchtablets.com/installADBdriver.
Used their instructions to load ADB drivers for Sony Xperia Tipo dual so that I could do debugging.
Install from the following links based on whether yours is a 32 or 64 bit Windows.

Go ahead and install the driver setup once downloaded.
Then simply navigate to Computer –> Device Manager –> Unrecognized android device. Update the driver and choose the browse option to point to the installation directory of the downloaded driver. Windows shall drive deep into the folder and install the software for you.
That’s it..Now your device is recognized as an Android device and also reachable via adb. Fire a adb devices command to confirm.
Hope it helps,
Just in case if the files are not available, please let me know.
