Hi all,

I have installed my 3DSlicer on Linux system but appeared the following message. Please tell me what went wrong?  
Operating system:Ubuntu 16.04  
Slicer version:Slicer-4.10.2-linux-amd64  
Many thanks

Can you change the working directory to where Slicer executable is located and run ./Slicer from there?
