When you say you launched a verification test, does that mean you created a new project to see if you’re having this issue elsewhere? I am a tad bit confused with the wording. Please make sure that you have UE 4.12.5 installed, Visual Studio 2015 with update 3 installed as well as the Windows SDK (build tools) installed as well. You can make sure that the tools are updated by following these steps: - Open Control Panel - Click on Programs and Features - Locate and click on Microsoft Visual Studio 2015 - Click update if it’s available to you - If not, click on modify and make sure the SDK is added. Make sure you restart after you’ve gone through all these steps. Looking forward to hearing back from you, thanks! ---

I desactivate my anti-virus and try to create some c+ project. Same issue… I launch the build engine, but when the project is created, the engine crash, and VS open. I try to open by double-click on the uproject, but I have the message I must rebuild the project sources. I rebuild but I have the message :" project could not be compiled. Try rebuilding from source manually." ---
