Hi! I’ve just downloaded 5.4.1 and I’m receiving this strange error if I click “Switch Unreal Engine Version” in the right click menu: ```auto Running C:/Program Files/Epic Games/UE_5.4/Engine/Build/BatchFiles/Build.bat -projectfiles -project="D:/_Unreal/UnrealProjects/HOWL/HOWL.uproject" -game -rocket -progress -log="D:\_Unreal\UnrealProjects\HOWL/Saved/Logs/UnrealVersionSelector-2024.05.01-19.07.36.log" Using bundled DotNet SDK version: 6.0.302 Running UnrealBuildTool: dotnet "..\..\Engine\Binaries\DotNET\UnrealBuildTool\UnrealBuildTool.dll" -projectfiles -project="D:/_Unreal/UnrealProjects/HOWL/HOWL.uproject" -game -rocket -progress -log="D:\_Unreal\UnrealProjects\HOWL/Saved/Logs/UnrealVersionSelector-2024.05.01-19.07.36.log" Log file: D:\_Unreal\UnrealProjects\HOWL\Saved\Logs\UnrealVersionSelector-2024.05.01-19.07.36.log Log file: C:\Users\Ares\AppData\Local\UnrealBuildTool\Log_GPF.txt Generating VisualStudio project files: Discovering modules, targets and source code for project... Total execution time: 1.95 seconds VisualStudioUnsupported x64 must be installed in order to build this target. ``` I’ve tried to delete all the unnecessary folders inside the project and rebuild it, change the engine association manually in the .uproject file but it just doesn’t work. Should I install a specific version of visual studio? I’ve also had issues with another UE5.4 project, it was compiling perfectly fine in 5.2 and 5.4 but in 5.4 I get this strange error saying: ` error C4668: 'ENGINE_MAJOR_VERSION' is not defined as a preprocessor macro, replacing with '0' for '#if/#elif'`, since “ENGINE\_MAJOR\_VERSION” should be a valid macro, I guess there is something wrong with my installation or with the latest unreal build tool ('cause I have no issues with previous engine versions) Thank you in advance! ---

You need visual studio 2022 with the latest updates to work with 5.4. The newest version is 64-bit only. ---

> [@3dRaven](#): > > You need visual studio 2022 with the latest updates to work with 5.4. The newest version is 64-bit only. I’ve been using visual studio 2022 since before it was officially supported by UE and it’s up to date and using the latest version, I really don’t know what could be happening here 😅 ---

> [@Ares9323](#): > > I’ve been using visual studio 2022 since before it was officially supported by UE And… this was the issue! Thank you for pointing me in the right direction! I had to delete the file I was using to force VS2022 with UE 4.27 (I even posted it as solution [here](https://forums.unrealengine.com/t/visual-studio-2019-14-22-27905-must-be-installed-to-build-this-target/150754/4)), this means it’s probably time to remove 4.27 from my pc 😅 EDIT: After being able to change the engine version I had another error saying: > UnrealBuildTool has banned the MSVC 14.39.33519-14.39.99999 toolchains due to compiler issues. Please install a different toolchain such as 14.38.33130 by opening the generated solution and installing recommended components or from the Visual Studio installer. I had to install a previous MSVC version (MSVC v143 - VS 2022 C++ x64/x86 build tools v14.38-17.8) and I was finally able to compile ---

This finally fixed such a perplexing issue for me as well. It was mainly down to deleting that xml file and letting unreal remake it. Really odd since if I made EGS verify my install of 5.4 (and after the update to 5.4.1) it’d generate the project files fine and even let me compile. But the moment I go back to 5.3 and then forward to 5.4 again, it’d come back with this same VisualStudioUnsupported error. Time to remove 4.27 as well until some project forces me back again. ---
