Unsigned app on Sierra

I have an older application (developed with xojo 2013 R2) that it is UNSIGNED and distributed via the web in a .zip file. With Sierra no longer works. I wanted to ask if is possible distribute an unsigned version and get it to work properly on Sierra. Until now, the only way that worked was to transfer the software from my computer (Yosemite) to Sierra with TeamViewer (nothing to do with internet download)
