I have recently updated my machine’s OS from Windows 10 to Windows 11. Everything was working fine. Initially, I have not tested the USB to Serial converter (Prolific PL2303TA USB to Serial Converter). After some days, I was inserting the USB to serial converter into my machine, and it was not working. I have seen the below error (PL2303TA DO NOT SUPPORT WINDOWS 11 OR LATER, PLEASE CONTACT YOUR SUPPLIER) when I see the device manager.
If you are also facing this issue, then this article (Prolific PL2303TA USB to Serial Windows 11 Problem) will help you.

I tried the driver PL2303_Prolific_DriverInstaller_v1_12_0. It worked the first time, but after I restarted the machine, I received the following error when connecting the console cable:
“PL2303TA DO NOT SUPPORT WINDOWS 11 OR LATER, PLEASE CONTACT YOUR SUPPLIER.”
Later, I tried the driver below, and it resolved the issue. My console cable model is BAFO BF-812.

The error comes backl next time I use the led programming
It worked, but same error came back next time I was using it.
Why isnt the fix saved?
Hi, you need to do the same process again. But you don’t need to download the driver again. You can pick the driver which you installed already in the device manager.
Well, it fixed the problem with “PL2303TA DO NOT SUPPORT WINDOWS 11 OR LATER PLEASE CONTACT YOUR SUPPLIER” BUT now it developed a new problem. can’t get into the program. I am changing a few things in the programing of the radio. (TK-8160) will not read anything gives me this message ” CHECK THE MODEL NAME AND MARKET CODE” never seen this before. Had windows 10 with no problems programming the radio. Now I have windows 11 with a problem programming this radio. I hope someone can help. My email address is kc1jys@gmail.com THANKS
It works on Windows 11 Enterprises OS
Is there a download location for this driver on Prolific’s website? A link to that would be very helpful. No offense, but as you already know: nobody should EVER download or install a driver or program or driver that doesn’t come directly from the manufacturer. EVER. A driver from a shared Google drive is not usable.
Once fixed with “PL2303_Prolific_DriverInstaller_v1_11_0” on Win 11 but suddenly failed.
Then I finally found here and it worked !
Thank you.

To anyone having problems, I found that if I didn’t run the .exe as administrator, the driver was never getting registered.

Thanks but it works for a day and then keeps crashing and I have to do everything from beginning or in the installation file run “Repair” Option and it fixes temporally till next day when same error appears. Do you have any thoughts on this?
Hi, you dont need to do everything from the beginning. There are two drivers. You have to select the driver that you have Installed now.
Thank you, you are awesome
