Prolific PL-2303 USB to RS232 on Vista


Another USB device would not install on Vista until I tricked it...

1) Download the Prolific PL-2303 XP driver from http://www.prolific.com.tw/eng/downloads.asp?ID=31

2) Unzip and then run the setup program. This will fail on Vista so run it on an XP machine.

3) The setup program creates a folder called PL-2303_loggedDrv in c:\windows\temp. This folder contains the signed 32 bit driver you need to install on Vista. Copy the PL-2303_loggedDrv folder to your Vista machine.

4) Plug the device into your USB port. The driver install will fail as it cannot find the driver on Windows Update. Select the "Search for driver on my PC" and point it at the PL-2303_loggedDrv folder.

5) The driver should now install correctly

I proceed point by point and installed the folder on my Vista machine, in C\windows\temp.

I pointed to it in the "update the drivers" in its "unknown device" window but still Vista answers it cannot find any 32 bit driver in it.

Actually there are three floders on the CD driver : BF-1284, PL2303 and USB232. O chose the PL-2303 Driver INstaller.exe in the PL2303 folder.

What did I miss ?

Hi there - works a treat thanks. I have linked to this article in the review of the product I put on Amazon. Hope that's OK! (If not, post a comment here). You've saved my network installations!

Thanks

Right click on file for properties;
on compability tab select XP/2,
"apply", "ok", and then run it.

Andrew, we are highly impressed with your trick wich we applied to install the driver on windows vista. This has relevied us from great panic and tension of not been able to download a simple driver.

We state that all is absolutely correct, tried and successful.
Many thanks and good luck.

Downloading and running the file PL2303_XP2KME98Driver_Setup.exe began with the usual installation routine, but the installer returned with "For Win98, WinME, Win2000 and WinXP Only"

Hi again, this worked for me before but now fails with the same error as "SecureType".
Paco's link works perfectly though: http://www.cooldrives.com/wividrforprc.html, no need for trickery anymore.

Thanks all.

The current incarnation actually runs and installs on Vista (although you have to accept it being unsigned/unknown origin) - thanks for being a pointer to the driver!

Thank you Andrew. Thank you very very much. Works like a charm. Vista just wouldn't install any of the drivers that were meant for it and none of the alternative links to working Vista drivers were helpful.
