12 years agoYou should have two shortcut options under your 'Altera' -> 'Quartus' Start menu - one for 32-bit and one for 64-bit. Given you've upgraded windows to 64-bit after you've installed Quartus, I suspect you don't.
You'll have to re-install Quartus as, I strongly suspect, the installer won't have installed the 64-bit version on your (previously) 32-bit machine. Regards, Alex
