We strongly recommend you use the latest FL Studio release here, that's why we give FL Studio owners Lifetime Free Updates! But if you are old-school that's OK with us too. You can download older FL Studio installers from the customer archive in Tech Support.
NOTE: If you buy the latest version of FL Studio, you can also unlock and use FL Studio 9, 10, 11 and 12, at no extra charge.
PREVIOUS FL STUDIO INSTALLERS
NOTE: Versions 8 and lower can't be unlocked because the licensing system is no-longer online. Your original license key will still work however.
If you have an older version, update with your 'Lifetime Free Updates'. If you have a backup flregkey.reg from one of these versions, it will still work, but we can no longer generate them, otherwise they will work in trial mode.
