Trying to install a Prolific Comm to USB driver for the cable. Use it if for switches etc.

I get the attached image error when trying to install in compatibility mode right at the end.

It's the x64 Win7 driver

Anybody have a workaround?.

Thanks,

Here;s the release notes from for the driver:

The driver is not for Windows 7. It should be very old, because I can see that it is for Windows 98 and Windows ME.

I got my end of life PL-2303 HXA USB serial converter to work on Windows8 64bit by doing the following. 

Visit the prolific site and get the following driver:

PL2303_Prolific_Vista_332102   (Yes, this is a Vista installer which will install on Win7 but not Win8) Go figure!

Install PL2303_Prolific_Vista_332102 on a Windows7 machine.  Once installed go to the C:\Windows\System32\Drivers folder and copy the file called ser2pl64.sys it should be 90KB if you use the 155KB file it will not work.  Do not use the 155KB file.  Copy the 90KB file to a USB drive

On the windows8 computer install the windows 8 driver PL2303_Prolific_Driverstaller_v_1_7_0  it's on http://www.prolific.com.tw/US/CustomerLogin.aspx use guest guest for user and password.

Run that installer then copy the 90KB ser2pl64.sys file into the Windows8 C:\Windows\System32\Drivers  you will overwrite any other that is there.

Reboot or disable and enable the USB to serial in the device manager of Windows8 and it should work. 

Hi there,

I need to get my EOL PL-2303 HXA working on windows 8, as well. Currently I get error 10 and the yellow triangle. My other computer runs XP Pro SP3. Anyone got any idea if I could do a similiar thing as RichM02145 has done for W7 to W8. ie are there files I could copy from my XP machine onto the W8 machine to achieve this. And how do I do it please?

Thanks ... John N

Hello. Great solution. Problem is I don't have a Win 7 or Vista install to grab the ser2pl64.sys file.

Would it be possible to attach it here? Perhaps zip and email me the file? Place it on a hosting service for downloading?

Thank you very much!

I was able to get the right 90K file mentioned above. However it will only let the device work if you turn driver signing off.

Hello,

Thank you for posting the above solution.  I would love to resolve the issue I am having with my USB-to-Serial adapter which is exactly like the one described above (driver not working on Win 8 / 64-bit machine).

I do not see the PL2003_Prolific_Vista_332102 driver on on Prolific's web site:

http://www.prolific.com.tw/US/supportDownload.aspx

Is that where you downloaded the 90KB Driver from?  Have they removed it since November 12 I wonder?

I did find the .zip and .exe on other web sites but was not able to generate said driver.

Thanks.

Kevin

Hello,

I can not find the PL2303_Prolific_Vista_332102 installer on Prolific's web site.  Where did you find it?

Thanks,

Hi,

Here is driver taken from win 7. Should work for both Win 8 X86/X64.

Don't forget to remove all not working drivers using device manager and check delete driver.

Hi,

I had a problem using prolific PL2303 for win 7 driver installer.

My device com was correctly installed (checked from device manager); but I couldn't transfer data using usb/serial connection on Win 7 64bit systems.

Here is what I found:

Driver date:    19/11/2009
Driver version: 2.0.13.130

Driver details:
File location                                  File version         Status
C:\Windows\system32\DRIVERS\ser2pl64.sys       2.0.13.130           OK         
C:\Windows\system32\DRIVERS\serenum.sys        6.1.7600.16385       OK


--------------------------------------------------------------------------

Driver date:    26/07/2012
Driver version: 3.4.36.247

Driver details:

File location                                  File version         Status
C:\Windows\system32\DRIVERS\ser2pl64.sys       3.4.36.247           NOT OK
C:\Windows\system32\DRIVERS\serenum.sys        6.1.7600.16385       OK

windows update is updating ser2pl64.sys from 2.0.13.130 to 3.4.36.247 (especially after the prolific installer has been installed; or when you hit the driver update button from the driver properties).

Manually overwriting the driver file ser2pl64.sys version 2.0.13.130 does fix the problem.

You can reach that file version here on our FTP.

Unbelievable that prolific can't do a proper installer or having drivers which work with latest windows updates...

HI there,

I've found an answer to this problem that works for me. I'm in the UK but I guess this solution will be available to others should they wish to take it.

This is a copy that I posted on another forum ( www.blackbox-solutions.com) a vehicle diagnostics site.

Hi Ronnie. I have located a lead that works with Windows 8. This is a windows issue and not an MSV2 issue, but will of course effect owners who purchase a new computer with Win 8. The lead has an FTDI chipset and I have connected it and reinstalled Vehicle explorer and it works. This is the link to where I purchased it. http://www.usbnow.co.uk and search for 48 ( this is their product number). I tried pasting the full link in here and although it shows on the input screen it doesn't come out on the 'preview post' for some reason. This is their AUM-100 lead. USB to RS232 with FTDI Chipset currently priced at 10.45 and delivered very quickly." Hope this info helps someone out there! Best wishes ...

Thank you. There is no other way, I've tried everything. You have to stick with Windows 7 for that chipset or move to Windows 8 with FTDI Chipset.

Just to document that I also got my GPS antennas (Pharos and GlobalSat BU-353) both working with Windows 8 32-bit using the same process.

The only difference is that I used the file named "ser2pl.sys" instead of "ser2pl64.sys".

Also, I placed the "ser2pl.sys" file into all of the following Windows 8 folders (found by doing a file search after the driver ver 1-7-0 install):

       C:\Windows\LastGood.Tmp\system32\DRIVERS\

       C:\Windows\System32\Drivers\

       C:\Windows\System32\DriverStore\FileRepository\ser2pl.inf_x86_2d105b2c9e5e9abe\

       C:\Windows\System32\DriverStore\FileRepository\ser2pl.inf_x86_5b1362ae5587f85d\

Worked perfectly - THANK YOU for this post!

No need to copy files to the drivers directory, etc. at all! I got my PL-2303 USB-to-Serial-Converter running on a 32-bit machine with Windows 8 as follows. My Windows 8 installation is in German, so I have to translate. 

• Go to the device manager and plug in your USB-to-Serial cable. The device icon should pop up in "COM & LPT" with a yellow mark that indicates that the device is not correctly installed.
• Double click to open its properties.
• Go to the "Driver" tab and hit the button to update your driver. 
• I see two options "Automatically look for new drivers" and "Look for drivers on your computer". Choose to look on your computer. 
• Now you may specify a path to look for drivers. Leave it blank and choose to select a driver from a list of drivers on your computer. 
• On my computer it shows four different "Prolific USB-to-Serial Comm Port" drivers. Choose version 3.2.0.0. 

The driver version 3.2.0.0 [31.07.2007] works fine on my Windows 8 32-bit installation, while the newer versions of the driver (3.3.5.122 and 3.4.36.247) do not. Hopefully, this helps someone out there. 

We put together an installer package that works around this problem by:

- Removing any configured serial ports using a Prolific Driver

- Removing the current Prolific Driver

- Reinstalling the latest Prolific Driver

- Overwriting either ser2pl.sys (32 bit) or ser2pl64.sys (64 bit) with a version of the same file from an older prolific driver

- Resetting the registry entry for serial device enumeration such that the next inserted device becomes COM3.

You can download it here: http://www.brightledsigns.com/downloads/plclean.exe

We've tested it on Windows 7, 64 bit, but it should work for anything XP and above.   Would appreciate any feedback on whether it worked for you (please include OS and whether 32 or 64 bit).

I've tried plclean.exe on Windows 8 Pro 64 bit with the PL-2303 HXA and unfortunately it did not work. I might also mention that it was a USB 3.0 port.

Vegan Fanatic pointed you here for Prolific.

CharliePel provided the user name and password to access support   guest\guest 

There, Prolific specifically addresses the issue and provides Windows 8 drivers, provided that you don't have a bootleg version of the product or the end of life version.

Prolific also recommends newer compatible products that will just plug and load.

Finally, as with all usb products, install the drivers first and then connect the device if Windows does not identify and install drivers after just plugging it in.

C'mon! Please read all that Prolific provides. End of story.

Jeddam, End of Life version, it will not work. Please visit Prolific for a solution.

Jeddam,

The device has only 32-bit drivers. Also, the Vostro has only 1 "power share" usb port, but the Dell product support doesn't say which one.

Regardless, Newegg has a device compatible with Win8 here with Win 8 drivers from the manufacturer here.

Don't do this

Move on to a product that will work.

hopefully that will give you a better result

I have a USB reader for SIM cards that uses that very chip as part of the product
