I was using MotionBox 64 bit on my LinuxMint 18.03 (based on Ubuntu 16.04) without any problems. Now I have upgraded to 1.4.0 and I get this error message at the startup:
./MotionBox: error while loading shared libraries: libpng16.so.16: cannot open shared object file: No such file or directory
Needless to say that libpng16.so.16 is in the directory.
If the issue cannot be solved, where can I download back the 1.3.0 version?
