I can't complete the download and debug of my STM32F401 Nucleo-64 MCU on IAR on Windows 11 because i get the following error "Failed the search for probes, ensure that the USB drivers are installed".

I have found that under the windows 11 control panel the ST-Link driver is not correctly recognized. Please see the attached picture about this.

There were no problems of this sort on windows 10, it only occured on windows 11. I tried to reinstall the driver without success.

Please right click on the ST-LINK and open properties. What is the error number?

Do you remember what exactly you did to reinstall the driver?

[GParr.1]

It says that the drivers are not installed (code 28), but i performed the installation as requested with IAR Embedded Workbench that has a specific section for the drivers installation.

I've also tried to download them from the net and install them myself, but the result was the same.

@GParr.1​ "i performed the installation as requested with IAR Embedded Workbench that has a specific section for the drivers installation"

If you've followed IAR's own documentation, and that hasn't worked, you should be taking that up with IAR.

Does the St-Link work with any other IDE(s) ?

[GParr.1]

The installation worked without any problems on windows 10 and i was able to upload programs and work on the STM32F401 MCU without any errors showing up.

Recently I had to switch to a computer with windows 11, i re-installed the IAR program from scratch like i did the first time on windows 10. IAR still works perfectly on the new OS, but the STM32F401 doesn't.

I haven't tried it with any other IDEs because i was told to use IAR for my projects.
