The xojo2016r4.1 can not runing on ubuntu 16.04 ? is seem to missing some file ?
It would help to know whether it is a 32 or 64 bit version, and what the error message said.
If it’s 64-bit Ubuntu 16, then you’ll also need to manually install the libraries noted on the System Requirements page:
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 libglib2.0-0:i386 libsoup2.4-1:i386 libgtk2.0-0:i386 libwebkitgtk-1.0.0:i386
and the ??? web licence can not compile 64bit app , such ??? and stand-alone ? !!!
