I downloaded UE5.3.2 and UE5.0.3 versions, and when I created a C++project in UE5.3.2, the project was able to start normally. However, when I created a C++project in UE5.0.3, I was prompted that it could not be compiled and asked if I wanted to open it in visual. Below is the error message. May I ask why this is.

Hi @zjy53,
I think the problem is related to your environment setup.
After installing Unreal Engine, did you install the additional C++ tools required to build the project?
I’m pretty sure I have installed everything I need, and if I hadn’t done it, the C++ project created with UE 5.3.2 wouldn’t have compiled. But the fact is that C++ projects created with UE5.3.2 compile, and creating C++ projects with UE5.0.3 tells me that they can’t. I even have .net core 3.1 and .net 4.6.2 target packages installed separately for UE5.0.3.By the way, I use visual studio 2022
Hi @zjy53,
Could you provide a more detailed log? The output shared so far appears to be the normal build initiation process and doesn’t indicate any build errors.
Are there specific features in UE 5.0.3 that you require, which are not available in UE 5.3.2, or are you trying to build an older project? If the latter, perhaps upgrading the project to UE 5.3.2 could resolve the issue.
Hi! UE 5.0 doesn’t support VS 2022. You need to have 2022 and 2019 if you want to use UE 5.3 and 5.0.
