I am using Quartus Standard 22.1.2 Build 922 but I'm not able to duplicate the issue.


I'll arrange a team meeting with you through email; please check for an email from me.

Prior to the call, could you please try the troubleshooting steps to eliminate any potential root causes:


  1. Try disabling any antivirus or firewall software temporarily, as they may be interfering with Quartus.
  2. Restart Quartus and your computer. This can help clear any temporary issues that may be causing the error.
  3. Verify that Quartus is installed with all the devices.
  4. Run Quartus as an administrator


Best Regards,

Richard Tan
