Being concerned that Microsoft will stop supporting Windows 7 in the near future, I finally bit the bullet and updated to Windows 10 4 days ago. I'm running Parallels on an iMac so I can continue to use VWS V15.00, p03 (and also Quicken). I was using WeatherLink 5.7 with a serial driver to USB connection, and after the Windows 10 installation, I did get the WININET error, and fixed that, but then found that my Davis VP2 console cannot communicate with the PC anymore. I ran an update and troubleshooter in the Device Manager, and it tells me the driver is OK (no updates), but also states that "This device cannot start (Code 10)", and also "A device which does not exist was specified".
A call to Davis Tech Support advised me to update to WeatherLink 6.0.3, which I have done, and I still have the same messages in the driver properties. Also, in the WeatherLink set-up walkthrough, it cannot communicate with the device, either. In trying to Test the port, it says "Error (-11) opening COM9. It is not present on your system, or is in use by another program".
Guess I should have stayed on Windows 7! Anybody have any idea of what is going on (or not) here? Thanks in advance for your assistance!
