I have the 391 usb to comport unit connected to a windows 10 platform. I can not install the driver correctly (using the “pololu-cp2102-setup-x64.exe”) as the I get this message: " The current language is not supported by the device driver installation wizard. Contact the vendor that provided you this package." If I place windows in “testsigning” (from a prompt: bcdedit -set testsigning on) mode then I can install the comport in the old way, but as soon as a change to normal mode the comport is not available and has the “!” appears in the device manager window. hope for a quick fix, thanks
I found a way to solve it. I press and hold the shift key down during restart and selecting “Troubleshoot”, “Advanced options”, “Startup Settings” and select “disable driver enforcement signature” it then let me install the driver using the “pololu-cp2102-setup-x64.exe”. Then I restarted the system and it work fine now.
I am sorry you had trouble installing our CP2102 drivers. Thank you for posting the solution you found.
According to an article from Silicon Labs, this issue is caused by a missing language code in
dpinst.xml. That article describes how you might be able to modify
dpinst.xml to include the correct language code for your computer.
For Windows 8 and later, a simpler solution would be to right-click on each of the two INF files (slabvcp.inf and plluvcp.inf) and select “Install”. This would directly install the drivers, bypassing the Device Driver Installation Wizard.
Thanks for you respond. Regarding the language code, I am using the
english version of windows 10 so… I guess if somebody has the time
they might look in to this. BTW if the language code issue which I find
hard to believe as I run the system in english; why does it work not?
just a mind teaser :-).

I tried to reproduce the issue here, on a Windows 10 computer using English, and was unable to. Are you still able to reproduce the problem on your computer? Do you still get that error message if you try to run the installer executable?
It was a newly installed windows 10 and I can not “go back” and try to
reinstall the driver as the system is in production now.
It will be hard to troubleshoot this error if neither of us can reproduce it. If the issue happens to you again and you would like help troubleshooting, please let me know.
