How to fix prolific usb to serial driver error code 10

This is a FIX for Prolific USB to serial on Windows 32 and 64-bit Operating Systems – Prolific PL-2303 Driver Fix (VID_067B & PID_2303).

I ended up writing this post when I connected the Prolific USB to serial device to my Windows 7 64-bit OS and installed the officially downloaded driver and found that it is not working and Windows has thrown the following error messages:

“No driver installed for this device”
“Device driver was not successfully installed”

Immediately I checked the Device manager and found the error code 10 with the following message:

“This Device cannot start (Code 10)”

The Prolific 64-bit drivers that Microsoft supplies via Windows Update, Versions,,, and will not work with most adapters and issues the generic “Code 10” error. Or, you may get no error at all, but your device will not work.

The only 64-bit driver I have ever found that works with all the “Prolific” adapters is Version The below installer program will remove all of the incompatible drivers, make a change so that Windows can never update the driver without your okay, and install the Version compatible drivers.


  • If your adapter was working prior to going to Windows Update, you can “roll back” to the previous installed driver and all will be well once again.
  • If you didn’t have a previous driver installed that worked, you’ll have to go through the process of removing any PL-2303 driver installation programs,the actual driver files, and the information(.INF) file BEFORE you are able to successfully install the correct driver.
  • In Windows 8, 8.1, and Window 10 are by default set to automatically update your drivers without your permission.

So, no matter how many times you remove the driver files and reboot, the next time you insert the USB-To-Serial adapter, Windows installs the newest non-working version again.
Make sure You disable the auto update for this Prolific driver at least before starting anything.
