Visual Studio and UE

I am trying to learn how to use UE Source.

I downloaded the Engine Source 4.25.

I am using Unreal Engine 4.25

I am using Visual Studio Community 2017.

When I try to build a Development Server following a tutorial using a base 3rd Person Template. Create a new C++ Class. Then i try to load the sln file and I get the error message of Invalid Win 32 when hit build…

Then i get the build screen show the following

Severity Code Description Project File Line Suppression State
Warning A custom tool ‘ResXFileCodeGenerator’ is associated with file ‘Properties\Resources.resx’, but the output of the custom tool was not found in the project. You may try re-running the custom tool by right-clicking on the file in the Solution Explorer and choosing Run Custom Tool. MemoryProfiler2

No Idea…

Any Ideas why this is happening please?

Thanks!

I think I realized what I am doing wrong.

I am new to Visual studio and source. I never actually BUILT the Engine in VS, So when i was trying a test project the engine was not compiled. Lets see what happens after building the engine from the source in VS.
