C++ project could not be compiled [Resolved]

When trying to create a C++ project, I receive an error saying The project could not be compiled. When looking through the full message, two lines stick out to me:

Using Visual Studio 2017 14.16.27042 toolchain (C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Tools\MSVC\14.16.27023) and Windows 10.0.18362.0 SDK (C:\Program Files (x86)\Windows Kits\10).

and

C:\Program Files (x86)\Epic Games\UE_5.0EA\Engine\Source\Runtime\Core\Public\Windows/WindowsPlatformCompilerSetup.h(19): error C2338: Visual Studio 2019 v16.4 or greater is required to build Unreal Engine.

So it’s using VS2017 and then telling me VS2019 tools are required. I checked the contents of my C:\Program Files (x86)\Microsoft Visual Studio folder and I have the 2019 build tools installed. So where do I go to configure the engine to use the 2019 build tools?

Also, here is the full error message in case there’s something else I’m missing:

The project could not be compiled. Would you like to open it in Visual Studio Code?

EDIT:
Solved, is the old dear friend BuildConfiguration.xml file, deleted it and all compiled well.

Thank you for letting me know about the BuildConfiguration.xml file in Appdata. I didn’t delete it, but I changed VisualStudio2017 to VisualStudio2019 in it and it worked.

Hi,
I only have VisualStudio2019 installed.
Where and how did you change from VisualStudio2017 to VisualStudio2019?

Sorry to resurrect this thread, but I am experiencing the same issue, however there is no \Unreal Engine folder in the AppData\Roaming folder…
