USB inf for win7 32bit and 64bit not working.

Dear All,

I have below INF which is said to be working for vista, win7 32 bit and 64 bit.
But i am not able to get the com port using this INF. I am getting code28 error.

Please find the INF i am using.

Can any one tell what is missing to run this INF successfully for win 7 32-bit and 64 bit.
