LibrePCB on Linux Mint 17

Trying to install on LinuxMint17, on laptop 32 bit. File:

Open and it asks for ok to excecute and install. Ok. But nothing happening ?
Is there a terminal command I can use ?

You can’t run 64 bit software on 32 bit operating systems.

And besides that, you are running an OS released in 2014 which no longer has active support, not even for security issues, you should install a newer OS.
