Limiting version 10.3 to work only for 2016/2019 or 10 is a VERY short-sighted, user-unfriendly solution. A huge amount of 2012r2 is used in the world. For example, only I have ~ 10 axigen servers running on 2012r2. I planned a purchase, but now I will look for another solution. I think I’m not alone. Tell managers and developers about this.
