This is for Zu3D Studio3 only (Zu3D M has the Media Library built in)
By default, the audio library will be installed to:
C:\Program Files\ZuLogic Ltd\Zu3D\Media Library\
In the single-user (ie, non-network) version of the Zu3D software, this path can be altered during installation.
While it is recommended that the audio library is installed to the local PC, it is also possible to install it to a network share, either via a mapped drive or UNC path.
