The driver is not for Windows 7. This can be beneficial to other community members reading the thread. If you read the release notes I included, The driver package supports many OS's. I used this exact driver package for Win 7 x64 Ent and it worked perfectly.
Do not use the KB file. Run that installer then copy the 90KB ser2pl Reboot or disable and enable the USB to serial in the device manager of Windows8 and it should work. Currently I get error 10 and the yellow triangle. And how do I do it please? Great solution. Problem is I don't have a Win 7 or Vista install to grab the ser2pl Would it be possible to attach it here? Perhaps zip and email me the file?
Place it on a hosting service for downloading? 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. Thank you for posting the above solution. Is that where you downloaded the 90KB Driver from? Have they removed it since November 12 I wonder?
Where did you find it? 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 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.
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. This is the link to where I purchased it.
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 lead. Thank you. There is no other way, I've tried everything. The only difference is that I used the file named "ser2pl. Also, I placed the "ser2pl. No need to copy files to the drivers directory, etc. My Windows 8 installation is in German, so I have to translate.
The driver version 3. Hopefully, this helps someone out there. 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. I might also mention that it was a USB 3. Vegan Fanatic pointed you here for Prolific. 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.
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. The device has only 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. Move on to a product that will work. In this dialog box you can enable or disable the FIFO buffer. I think that the most difficult for most of the people is how to avoid windows 8. There is a special case that, the operating system is a bit system, but you are not sure whether the program is bit or bit.
If you encounter this situation, check the file path to see whether there are any other files located in. If yes, please check the properties of these files, and you will know if the file you need is bit or bit.

All my other software linked to the observatory works fine, apart for SKY X astronomical. I had to load an old version to get the scope to link up but its not stable.
Do you know how I can fix this? Best regards Rick Bromley. Reply: I don't think we can solve this problem simply by overwriting files. This is an incompatibility between the driver and the operating system. If your original WIN 7 is bit, and now WIN 10 is bit, then I suggest you to download the bit program installation package from the official website. For this, you can go to the official website of Microsoft. By example:. I have tried with 3. If you don't have the old versions of drivers, you can tried to install them from the minidisc provided with your product.
Launch this program, it will install the driver. But, as soon as you plug the device on USB port, you W10 will revert to the latest version 3. If you watch the configuration panel, you will see the COM port coming OK, but then switch off because of error It don't care, because the old version is now available in the list, and you can proceed as mentioned above.
Once manually set, the device driver remain in the 3. Edit: The procedure above works, but only temporary. Each time you turn your computer off, the latest driver is reloaded due to windows auto-update or if you unplug and plug again the device into USB port. To avoid that, a recent turnaround exist and has been published by Microsoft.
It's a tool named wushowhide. It allow to inhibit the auto-update for a particular program or driver Prolific in our case. For more informations and where to download this tool, take a look at this article : KB I have tested it and it work fine.
The only problem with it, is that, it reload the latest driver when you plug the device on a never used USB port. So, if you change place of connection, you should manually set the driver to 3.
