Hello everyone,

I just installed the 4.7.2 version of the UE4. When I create a new blueprint project, it works. But if I want to create a new c++ project, I get the following error:

Failed to generate project files. Log output:
Running C: / Program Files / Epic Games / 4.7 / Engine / Binaries / DotNET / UnrealBuildTool.exe -projectfiles -project = “D: /WIP/10_UnrealEngine4/MyProject/MyProject.uproject” -game -rocket -progress

UnrealBuildTool Exception: ERROR: UnrealBuildTool Encountered an error while compiling source files

Also, I cannot compile a C ++ project created with an anterior engine version because a lot of includes cannot be opened. With 4.6.1, I have no problem.

ps: sorry for my English.

One thing I would check is whether you have two WebBrowser and CEF3Utils folders. They used to be in Engine\Source\Developer and were moved to Engine\Source\Runtime in 4.7. Some people who have gone through the upgrade process have ended up with both of them still remaining, though I don’t think I’ve seen this exact error message before. If you do have both, try deleting the versions that are in the developer folder.

Thank you for your answer. I reinstalled the 4.7.2 version, and everything works fine.
