Quartus prime lite - Can't create work directory - Quartus prime lite - Can't create work directory Hi, I just started using quartus lite, so I can't understand some technical words. I'm glad if I get your support. I opened "New Project Wizard" and filled in the blanks as followings. Q. What is the working directory for this project? >> C:\intelFPGA_lite\20.1\sample And I clicked "next >". then PC answered, "Directory "C:\intelFPGA_lite\20.1\sample" does not exist. Do you want to create it?" I answered "Yes". then PC answered, "Can't create working directory "C:\intelFPGA_lite\20.1\sample". So I would like to know what is the cause of this error message. Replies: Re: Quartus prime lite - Can't create work directory Hi sstrell, thanks a lot for your reply. I changed the location from "C:\intelFGPA_lite\20.1\sample" to "C:/intelFGPA_prj/20.1/sample". Then somehow I successfully created the directory! Thank you for your advice.

Try putting the project directory at a location you have access to.
