Issue:
If your quartus2.qreg file includes the
line:
General\Check_for_New_Info_Mess
age_at_Startup=Yes
and you attempt to start the Quartus II
GUI, startup fails.
Workaround:
In your quartus2.qreg file, change the line
General\Check_for_New_Info_Message_at_Startup=Yes
to
General\Check_for_New_Info_Message_at_Startup=No
The quartus2.qreg file is located in ~/.altera.quartus.
