Bootstick does not work - neither on 2015 nor on 2016

I have two Macs - one with Yosemite 10.10.5 the other one with the latest EC beta. But no matter on which Mac I create the bootstick and which Acronis version I use - Acronis won’t start. The stick works on both Macs and I can also restore using TimeMachine, but not with TrueImage. When I click on the Acronis App in the restore menu nothing happens. The continue button grays out, but is black again after a few seconds. The same when I start using the menu. On both Macs with both OS’s and with TrueImage 2015 and 2016. Whats wrong with TI?
