I deleted my workspace file to recreated the project, but when I attempt to start up the Nios II IDE, I see the splash screen, then a small dialogue box appears, saying:
"An error has occurred. See the log file C:\User\user\.altera.sbt4e\18.104.22.1685-windows64\configuration\1603861355640.log"
I also reinstall quartus, but it didn't work.
(my environment: Quartus prime lite 18.1 windows10-64bit )
Hope any advice will appreciate.
