That is actually a very good idea to make sure and not take any risks when the trial versions have a deadline. However, I have to add I have actually once had version 13.0.0 (32-bit) installed on my PC. Then due to some reasons I installed another windows (64-bit) and installed version 13.0.3 trial on it. When I deleted v 13.0.0, 24 days were left till the deadline, and when I installed v 13.0.3 the next day, 23 days were left.
