A: Starting with the Nios® II EDS in the Intel® Quartus® Prime Pro Edition software version 19.2 and Intel® Quartus® Prime Standard Edition software version 19.1, the Cygwin component in the Windows* version of Nios II EDS has been removed and replaced with Windows Subsystem for Linux(WSL).

So to run the NIOS II Command Shell properly, you need to follow the steps below to install.

Fix

  1. Open PowerShell as Administrator
