The raw driver files should be the same. You'll need to use the directory that matches your operating system.
If you have a 32-bit installation of Windows, start from the X86 folder, if your Windows installation is 64-bit, start from the x64 folder.
From there, select the folder that matches your version of Windows (XP, 2000, Vista, 7 etc etc).
If you don't know if you have 32-bit or 64-bit Windows, find the icon for My Computer (either on your desktop, or in Windows Explorer, the file manager). Right click on My Computer, select properties. Search around the window that appears, and it'll say 32- or 64-bit somewhere.
You're definitely in bootloader mode when connecting the X7 to your PC, as in holding down the reset switch on the bottom of the device?
If all else fails, try the DriverInstaller2014.rar archive, and run the EXE in there.
