I replaced old executable file with the new one but it didn't solved the problem. One robot is inside elevator, door is closed, I press End Turn icon and nothing happens.
Was the executable file the only one that changed?
Yes, the only change is in the executable. Alternatively, you could copy the save files - save.list and S0, S1, etc - into the directory of the new version.
Open the elevator door and move the robots onto it. Just walking over the door should trigger the exit.
