Any ideas? I’m no programmer and really don’t understand what to do. It was supposed to be easy to upgrade but I know it’s beta, so I bring this in for you to notice.
Yes, I have installed latest .NET which is 5. So it only works with 3?
EDIT: after installing the one on the link it worked. BUT. and this is a huge BUT: I only got that direct link to download after first having to guess and install v5 of .NET, then the message changed and told me to install that particular one. This should be fixed,
I had a similar problem with upgrading from 4.27.2 to 5.0.
The first message when upgrading my project was like:
Project files could not be generated. Log output:

A fatal error occurred. The required library hostfxr.dll could not be found.
If this is a self-contained application, that library should exist in [C:\Epic Games\UE_5.0\Engine\Binaries\DotNET\UnrealBuildTool\].
If this is a framework-dependent application, install the runtime in the global location [C:\Program Files\dotnet] or use the DOTNET_ROOT environment variable to specify the runtime location or register the runtime location in [HKLM\SOFTWARE\dotnet\Setup\InstalledVersions\x64\InstallLocation].
The .NET Core runtime can be found at:

I think here it is important to choose the version that is compatible with your installed Visual Studio version. I choose .NET 5.0 because it has the same version number as Unreal 5.
And… it’s made for my installed Visual Studio 2019.

I opened the link and installed the “.NET Core CONSOLE Runtime”. Or is it the DESKTOP version that you also need to create Windows builds later ?
After a Windows 10 restart the project upgrade from Unreal 4.27.2 to 5.0 worked just fine.
On Windows 11 I also got this error:

ERROR: Could not find NetFxSDK install dir; this will prevent SwarmInterface from installing. Install a version of .NET Framework SDK at 4.6.0 or higher.
To fix it you need to install .NET Framework SDK. You can do this by running Microsoft Visual Studio Installer, then on “Modify” next to the installed version of Visual Studio and switch tab to “Individual Components” and check the latest version of .NET Framework SDK.
