It seems something goes wrong during precompiled headers generation. I get errors like:

Followed the instructions in Readme.md.
Deleted the intermediates (Engine\Intermediate\Build), cleaned the solution… the problems remain.
The same thing happens on release, promoted and branches

Any workarounds?

Hi there,

UE4 does not yet support update 3 properly, so that is most likely the reason for the build errors.

You can find more info, and potential workarounds here:

Thanks,

Anyone know how to revert back to update 2? Can’t do anything while this issue exists…

Any solution ? I try this solution, but didn’t work for me :/…

Hey Everyone,

Following the directions in the post by Infected_Post here allowed me to uninstall/reinstall VS2015 Community without Update 3. It does not appear to include a means of obtaining Update 1 or 2, but you should be able to continue using your code projects.

Cheers

VS2015 is very long to install… Epic games don’t give more news about ?

We do plan to address this compatibility issue as quickly as possible, however for now the best options are to avoid updating to Update 3 if possible or, as mentioned, using the instructions from Infected_Post to remove Update 3 until a fix for the problem can be put in.

Ok, how to stay informed ? I can wait, but if the issues with VS2015 update 3 still here in the end of the week, i prefere now to reinstall VS2015. Thank you for your quick responses.

The best way to keep up to date on changes to the engine are to review patch/release notes for newer versions as they become available. There is no time frame yet of when a fix for the Update 3 issue will be implemented and I would suggest going ahead and reinstalling for the time being.

I found a workaround - basically remove 4599 and 4609 warning to error pragmas in Engine/Source/Runtime/Core/Public/Windows/WindowsPlatformCompilerSetup.h.

Here is a commit you can cherry-pick:

Then i’ll reinstall VS2015, thanks for the help.

Dude, 4605 not 4609.

4.12.5 fixes this for Windows, but not for XboxOne. The same changes are needed in Engine\Source\Runtime\Core\Public\XboxOne\XboxOneCompilerSetup.h.

Nah 404 error
