I just reinstalled visual studio with C++ and this happened… Anyone know whats wrong?

This usually works to resolve Visual Studio weirdness:

Close UE4 Editor
Delete everything in /Intermediate/ and /Saved/
Open UE4 Editor
File -> Refresh Visual Studio Project
Open Visual Studio project, attempt to compile

Apparently Visual Studio updated this morning, and the new update breaks Unreal.

Now I’m getting a new error:

This is the key information in the log file:

This means that you installed a new version but are trying to re-use compile results from an older (or at least different) version.

Did you make sure to re-generate all source files after removing the intermediates?
Re-run GenerateProjectFiles.bat in the root of your unreal engine.

I just created a new C++ project and get the same error at line 261 that Snowl0l gets. I have Visual Studio 2015 Update 3 RC. Do you suppose that that has something to do with it. I just tried creating the project in v4.12.3 as well as v4.11.2 and get the same results when the project creation wizard runs. I can create a Blueprint project just fine.

**** it, going back to vs 2013…

going back to 2013 didn’t work. Im dunzo

anonymous_user_066609ca · June 28, 2016, 10:06pm

New user here, I thought I might be able to add to this. In the same situation as NCEdElliott’s post, I found that trying to recompile a modified blueprint (ie adding a new class) causes that same “command line argument number 261 does not match precompiled header” error.

This contains a workaround if you’re working with engine source.

VTalyh · June 29, 2016, 7:00am

opening the WindowsPlatformCompilerSetup.h file in source code (this won’t correct it for the binary version of the Engine, unfortunately)
remove 4599 from the table of warnings at the top
add #pragma warning(disable : 4599) below the list
