Quartus II standard 18.1 with Windows 10 Platform designer generation error - Quartus II standard 18.1 with Windows 10 Platform designer generation error Hello, I am trying to migrate a Quartus II project from Quartus 13.0 under Windows 7 to Quartus prime standard 18.1 under windows 10. My original project contains a QSYS instance with DDR2 SDRAM Controller. When I compile the qsys file in Platform Designer, it generates the following error: Error: s0: Error during execution of "{C:/intelfpga/18.1/quartus/../nios2eds/Nios II Command Shell.bat} make all 2>> stderr.txt": child process exited abnormally ..... Error: s0: Le sous système Windows pour Linux n'a pas de distribution installées. When doing the same under windows 7, it works fine. Do you know how to solve it?

Check with the latest version Quartus. Try by reinstalling the Quartus along the default path. If still facing problem Update/reinstall Windows and Quartus. https://www.intel.com/content/www/us/en/programmable/support/support-resources/knowledge-base/solutions/rd02192013_986.html Regards Anand
