Need help with visual studio for Unreal Enginer 5.3

[Blackforcedragon]

I’m trying to code with C++Using Unreal Engine 5.3 , but Visual Studio 2022 won’t build/ compile my codes, but Live code will compile my codes.
If I create a new c++ project, and try to build (no edit or add any code) Visual studio try to compile, then it fail, but Live code never fail.

But Visual Studio will compile Unreal Engine 5.5 codes,

so, is it a module or something I need to make it work in Unreal Engine 5.3 and compile the code?

Link to project:
Dropbox link

Visual Studio 2022, 17.13.6

error before trying to compile:

Live code is a “different beast”. Try to first compile the engine at least once before going in with Live code.

You should be able to create an empty project and compile that.

Try going through these steps and say if you manage to build: Setting Up Visual Studio Development Environment for C++ Projects in Unreal Engine | Unreal Engine 5.5 Documentation | Epic Developer Community

I did follow the documentation you linked first.

the thing is, 5.3 don’t work,l but 5.5 does work.

I did make an empty c++ project in unreal engine 5.3, visual studio open, i did click build, and I get warnings an errors

UE5.3 requires a specific MSVC version, if you have a recent one, it might fail like the errors you are receiving.

For only 5.3 to work, you need MSVC 17.6 from Visual Studio Installer:

If that still doesnt work (double check in the output log which msvc version it using)
Do this manual workaround (set the proper msvc ver for 5.3)

I'm having a really frustrating issue with Unreal Engine 5.4 and Visual Studio 2022 when trying to build my project

You will need to use only MSVC 14.38.33130, newer version might cause these issues. Try to remove any newer version as well from Visual Studio Installer. If that still doesnt, do this workaround: [image]
