Arduin mini Pro Board AT328 Not shows COM port

hi , one of my friend brough Arduino pro mini AT328P board along with FTDI 1427 for connecting HC-06 BLE module, he left

then i took initiative for this project

i set up the connection

FTDI Arduni pro mini

5V - 5V TXD - RXD RXD - TXD CTS - GND GND - GND DTR - DTR

FTDI 1427 has switch to 3v3 & 5v (http://modtronix.com/pgm-ftdi-basic.html) i kept 5 volts

Problem is when i connected mini pro through FTDI 1427C to my PC

First : FTDI 1427 drivers installed successfully THEN

Next mini pro Device drivers is tried to install but it could not install drivers successfully

then no COM port available in my arduino IDE Tools

naidu003: Next mini pro Device drivers is tried to install but it could not install drivers successfully

The what? The Arduino Pro Mini itself has no drivers at all. All the PC sees is the FTDI converter. What's connected to that is just Serial and up to the programs that want to use it.

So if you don't see a COM port the drivers of the FTDI failed to install.

Is it a reall FTDI or is it from China?
