Can you provide more details? For example, if the MSI installer is failing a log would help. This link will describe how to get logs for most cases:
My UDK installer crashes without error, I have checked it through task manager.
I’ve tried compatibility mode with Win XP SP 2 & 3, running it as administrator, but still it’s not working.
Hi KennyDBacon,
I want to clarify something to avoid any confusion:
The UDK is the free version of the older Unreal Engine 3.
However, the AnswerHub and Forums at UnrealEngine.com are dedicated to the newly released Unreal Engine 4.
So are you experiencing an issue with the UDK, or with the UE4?
Thanks!
