The author tolds on the issues board of the project, that RTL-SDR is not natively supported. One must use a GnuRadio backend (see bug #139). Any volounteers is needed to add native rlt-sdr support !

Please direct me how to make URH work on my Win10 64-bit.
Thank you and thank you for the great piece of software!

This comment is very old, RTL-SDR works of the box on Windows natively. Just use the exe installer on the releases page: https://github.com/jopohl/urh/releases/tag/v2.9.2

Thank you for reply. On mine it's ont working out of the box. On my machine RTL-SDR option is grayed out. It is not enabled. Kindly see attached.

On the screenshot you posted RTL-SDR is enabled through native backend...

If so i don't understand why it's not working when i want to record any signal? Why is shows "not available"?

Please make a screenshot.

I'm getting eeror code -12:

So the native support is working. This error code comes from the RTL-SDR driver. Did you google it? Some things that come to my mind:

1. Try run URH as administrator
2. Try a different USB port
3. Not sure if this is needed for RTL-SDR but for HackRF you need to install driver with Zadig. Might be worth a shot.

Bull's eye! Point number 1. Run as administrator! Now it's working. Thank you.
