Unreal 4.8.0 won't build

Our project was on 4.7.6
I got the new 4.8.0 Preview 1

It did the conversion.
Changed the one uint32 to int32 in our c++ files. (It complained about that otherwise)

Then I deleted the Binaries, Saved, and Intermediate folders.
Then generated the Visual Studio project files.

If I run unreal it ask to build UE4Editor-tdl.dll
It then fails and tells me to do it manually.
I go into Visual Studio and it succedes there but no tdl.exe is made etc.
I then clean and try again, same results.
Then I go into one of our c++ source files and change a line slightly to force a rebuild.

I then get 100 errors from intellisense and it won’t build.

It complains that the generated.h files do not exist.

The log file from when I try to run the editor…

etc.....

Any ideas?
(We are stuck on this and will have to revert back to 4.7.6 tomorrow if this is not solved.)

The silence is deafening. No answer.

We will have to go back to Unreal 4.7.6 now.

same problem here

The latest Unreal 4.8 works fine now.
