How to Activate Helix Native
Download the latest version of Helix Native at http://line6.com/software/.
Run the Helix Native installer. We suggest you temporarily disable all third party antivirus programs during the installation. During the install, take note of the VST3 and AAX Plugin folder locations. If you choose to install the PC VST2 plugin, you will be able to choose your own folder location. On Mac, VST2 is installed at /Library/Audio/Plug-Ins/
