I need some help on Ubuntu.

Initially I downloaded and installed Ubuntu 17.04 32bit version and I was able to use the instructions to build the EquiTrader-qt executable and I can run it from within Files. Properties on this file indicates that it is an executable.

I since have decided to install 64 bit of 17.04 but now I am having some problems building the executable.

The build process completes and from within the terminal i can run ./EquiTrader-qt and the wallet does open. The bar on the left does show the EQT icon twice which it did not do on the 32 bit version.

However, the EquiTrader-qt file when looking at properties in Files indicates that this is a shared library file, and no matter what I do I can't get it to execute from Files.

What gives?
Thanks
