Using Windows 10 version 1803 with dongle license

Technical Note 180502



11/12/2018 4:57 PM


We have discovered that USB dongles cannot always be found on Windows 10 version 1803. That is a problem with dongled licenses.


The message from IAR Embedded Workbench can look like this:

Failed to obtain feature 'ARM.EW.DEBUGGER'

It can also happen during a License Activation.

Missing dongle: The dongle for "Product" (S/N 1234) was not found.

  3. Right-click the IAR Embedded Workbench shortcut
  4. Choose Properties
  5. Open the Compatibility page
  6. Select Run this program in compatibility mode for: Windows 8
  7. Click OK

This issue has been corrected in IAR Embedded Workbench for Arm version 8.30.1 and newer. For older or other versions of IAR Embedded Workbench, use the workaround. The issue has been acknowledged by our License Management Partner and will be corrected in future releases.
