If you are using an IAR Embedded Workbench released before June 2018, USB dongles may not always be found on Windows 10 version 1803, 1809, 1903, and newer. This is only a problem for dongled licenses when using an older version of IAR Embedded Workbench.
The message from IAR Embedded Workbench can look like this:
Failed to obtain feature: "ARM.EW.DEBUGGER".
The feature is not licensed to run on this machine.
Could it be a dongle problem? Status code 0x6.
It can also happen during a License Activation.
Missing dongle: The dongle for "Product" (S/N 1234) was not found.

The easiest workaround is to install a later version of our Embedded Workbench, released after June 2018, which has a fixed USB-driver included. That driver will then also work with older releases, prior to 2018. Alternatively, you can run the old Embedded Workbench in Windows 8 compatibility mode:
IAR License Manager
Perform the corresponding actions on the LicenseManager.exe icon.
Perform the corresponding actions on the eclipse.exe icon.
All IAR Embedded Workbench releases from June 2018 and later include the correction. For older versions of IAR Embedded Workbench, use the workaround.
