Are you using the visual studio version 2015 because unreal 4.10 need visual studio 2015

Hey-

If I understand your post correctly you have a project that you’ve converted from 4.9.2 to the 4.10 preview, correct? As Charles pointed out, using 4.10 requires Visual Studio 2015 to compile code projects. Let us know if you still have problems after installing VS2015.

Cheers
