Nitrokey 3A NFC Not Detected by Nitrokey App 2 on Windows 11

Hello,

I am experiencing an issue with a new Nitrokey 3A NFC that I recently purchased.

The device has not been set up or initialized yet and is being connected for the first time. However, it is not detected by Nitrokey App 2 on my Windows 11 system.

For reference:

  • The Nitrokey is brand new and has not been configured previously.
  • Windows 11 is fully up to date.
  • I am using the latest available version of Nitrokey App 2.
  • The USB ports on my computer are functioning properly and have been tested with other devices.

Could you please advise on any troubleshooting steps or let me know if there are known issues that could cause a new Nitrokey 3A NFC not to be recognized by Nitrokey App 2?

Thank you for your assistance.

Kind regards,

guefi

Can you please check if the device is recognized if you execute Nitrokey App 2 as administrator?

Due to a compatibility issue in firmware version v1.9.0, Nitrokey App 2 does not recognize the Nitrokey on Windows if it is not running as administrator. This has been fixed in v1.9.1, so you should be able to use the device normally after a firmware update.

Ok, the problem is fixed. :+1:
