LNK1104: cannot open file \\MYPATHTOBINARIES\UE4Editor-UnrealEd.dll'

Hello everyone!

I cloned the AlienRenders DQS repo and source built it with theUGC project examples.
It was and is all working fine, but I can’t seem to make code changes to any of my cpp files, because it gives me a ton of linking errors, basically for nearly all of the modules.

A couple of lines from the editor log:

Tried doing a CRTL+SHIFT+B in VS with Development-Editor config, and I get similar error messages, but it seems to do some compiling work…

The compilation process takes ages to complete even though I only make slight changes to the project.

In VS right click the project and hit UnrealVS quickbuild and choose 64 bit Development-Editor.
That fixed it for me!
