without any exception or conditions ??

If you purchase the discounted “upgrade” version from LE 6, you will receive a USB-eLicenser and a new activation code. When you enter your new Artist 7.5 activation code in the eLCC, it will “look” for your LE 6 license. As long as you have the eLCC installed with your valid LE 6 license you can download your new Artist 7.5 license to the USB-eLicenser.
