7 years agoThis is possible some of the user Quartus files are corrupted.
You can either create a new user on your PC and launch quartus from there
Or
For existing user, locate following files in your user directory.
Create a backup of these files and then re-launch the Quartus
.altera.quartus
quartus2.ini
quartus2.qreg
