I’m trying to upgrade a copy of a project from 5.0 to 5.1 and have hit the following problem. It’s a C++ / blueprint mixed project, and so it’s not a simple upgrade.

- I opened the project in 5.1 and got it to upgrade a copy
- It copies but does not build, so I go to the new folder, right click, and select ‘Generate Visual Studio project files’
- It then fails with the following error

```auto

```

Can anyone shed some light on this, what I need to download / install?

Thanks

Found the solution. For anyone else having this problem:

- Open the Visual Studio Installer
- Select ‘modify’ next to Visual Studio 2022
- Select ‘Individual components’
- Search for ‘MSVC v143 - VS 2022 C++ x64/x86 build tools (v14.30-17.0)’ and check the box
- Click ‘Modify’ to download the package
- Wait for it to install
- Close Visual Studio and Unreal (if open)
- Delete the **.vs** , **Binaries** , **Intermediate** , **Saved** folders and **YourGame.sln**
- Right click on the uproject file and generate the visual studio files

…and it should all work

I had same error when switching to UE5.3 and solution provided by Godwhacker didn’t work.  
To resolve the problem I had to remove one file - C:\Users\YOUR USERNAME\AppData\Roaming\Unreal Engine\UnrealBuildTool\BuildConfiguration.xml  
Then re-generate project files. This way unreal created a new config file with proper settings.

Thanks for that, had the same problem here when creating a new UE 5.3 project.
