How to activate the WE2 upgrade.PDF
Log in to your “myWaldorf” account. After logging in go to “Redeem Coupon”. Here you can enter the coupon code you’ve received from us or after the purchase.
Afterwards go to “License Keys”. Here you’ll find your activation data for the upgrade. Since you’ve already installed the Waldorf Edition LE you don’t have to run an installer.
Open the PPG2 plug from the WE2LE version in your DAW.
At the top right, click on the window “upgrade to full version”.  Here you can enter your upgrade activation data.
