Ahh - you're using CSR's tools, not the windows built-in ones?
As you're using an external CSR dongle you might need to try and get some Windows 10 drivers for it? It's possible that if you installed older driver/software the CSR tools don't make it available using the Windows 10 APIs.
To be honest as you're using an external dongle the easiest solution might be to:
Uninstall the CSR tools and drivers
Follows the Windows 7 instructions to run Zadig and change the CSR dongle over to use the WinUSB drivers
The Web IDE should then run and connect without you having to pair with Windows - it'll be talking to the dongle directly without going via the Windows 10 APIs.
