Simple question: Should I uninstall UDK Development Kit 2015 if I already have Unreal 4? Does it make any difference?
That depends on you, i would leave it for historical reason as downloads for UDK is hard to found, atleast leave installer. One thing to note is that Epic don’t support it anymore and if im not mistaken technically you can’t distribute games UE3 legally without Epic special permission.
That wasn´t my question actually. Is it OK / safe to uninstall it or not? Will I have problems if I do? The Unreal 4 engine will be compromised?
