HiAll.Im trying to upgrade to WIN7 and a 64bit machine. I have XPSP3 on a 32 bit and my PL2303 works fine. Searched the forum and internet, downloaded and tried to install but WIN7 doesnt ven find the driver with Windows upgrade. Found E1boxUS17 doesnt work, PL2303 driver installer doesnt have the installer wizard. Any link, THANKS.

Are you sure that it is not automatically recognized by Windows 7 ?

Are you very sure that it is not a counterfeit FTDI chip ?

Can you retrieve the PID and VID numbers of it (with Device Manager or in linux with 'lsusb') ?

Any "Arduino" with a PL2303 is non-genuine; there was never an official Arduino manufactured with that chip.

The question is whether the PL2303 is genuine (in which case it should work with built-in or Prolific-provided driver), or counterfeit (in which case, it may take more effort to find a driver that works.) I don't know how to tell, beyond the info in the link I posted earlier.
