Did you update your X7 to the X7 CE v2.0.0 firmware. If so, copy the update.zip to a "USB" stick not your MSD card. Make sure you can open the zip file first on your computer using WinZip or WinRAR. If it opens or you extract it with no errors then the zip file is ok to put on the USB. When you connect it to your X7 it should detect it and ask you to install. Hope this helps.
