In order to install this product you will need to download its corresponding setup archive to the computer you are planning to use this product on (Internet connection is not required for the product to function).
For VST plug-ins on Windows platform:
You should unpack ZIP file you have downloaded into the "VstPlugins" folder, the one which is connected with the audio application you are using and where this application expects VST plug-ins to reside (it is also suggested to create the "Voxengo" or "Voxengo64" for 64-bit plug-ins sub-folder there, and unpack the archive there instead of the main "VstPlugins" folder).
For VST/AudioUnit plug-ins on Mac OS X platform:
You should open the DMG disk image and drag & drop the "component" (or "vst") package from it into the corresponding plug-in folder located in the "/Library/Audio/Plug-Ins/" folder on the harddisk (the "component" package should go to the "/Library/Audio/Plug-Ins/Components/" folder while the "vst" package should go to the "/Library/Audio/Plug-Ins/VST/" folder).
Note that you need to install AudioUnit plug-in for use in Logic Pro, GarageBand and other AudioUnit-compatible audio applications.
After this has been done you will need to order your audio application to rescan plug-ins, or if that option is unavailable you will need to re-start this application. Note that plug-ins cannot work without an audio application that hosts/loads them.
