I already own HS6. Is there no way to download HSE3 without getting an email and activating HS all over again? I know it may not be common for users to have all 3 versions but I’m developing libraries and I’d like to test them in all 3 versions before I release them.

The email thing is required because they have to create a MySteinberg account for you if you don’t have one, and to send you an activation code if you don’t own Cubase. If you already created a MySteinberg account, just use the same email. The rest of the process is completely painless.

As Romantique says, there’s no need to do the activation if you already have Halion 6 installed.

Just use the download link, install and all will be tickety boo.
