You can do this manually from File -&gt; Preferences -&gt; Settings (assuming you use Windows) and then search for &quot;nRF&quot;. Then set the Nrf-connect: Topdir and Nrf-connect &gt; Toolchain: Path.</p> <p>Alternatively,&nbsp; you can choose from a list and get the configuration updated for you by using the Quick Setup GUI which you find here:</p> <p><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/select_5F00_qs.PNG" /></p> <p>Then select the SDK folder and toolchain folder:</p> <p><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/qc.PNG" /></p><div style="clear:both;"></div>
