Our new software V_II manages its lightshows in the folder "../YourComputeHomedirectory/TheLightingController_II"
while our software version V_9 manages its lightshows in the folder "../YourComputeHomedirectory/TheLightingController".
These are two different folders, so V_II will not damage your V_9 lightshows and vice-versa.
Booth software versions can be installed on the same computer without damaging the lightshows of each other.
