Prisoner416 Posted December 1, 2022 Share Posted December 1, 2022 After upgrading my hard drive, Launchbox no longer loads. It shows a busy sign for less than a second after clicking, then nothing. Event viewer shows the following log: Description: A .NET Core application failed. Application: LaunchBox.exe Path: C:\Users\Doctor Who\LaunchBox\Core\LaunchBox.exe Message: A JSON parsing exception occurred in [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App\3.1.31\Microsoft.WindowsDesktop.App.runtimeconfig.json], offset 0 (line 1, column 1): The document is empty. Invalid framework config.json [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App\3.1.31\Microsoft.WindowsDesktop.App.runtimeconfig.json] Quote Link to comment Share on other sites More sharing options...
DeadVoivod Posted December 1, 2022 Share Posted December 1, 2022 Missing .NET framework perhaps? Quote Link to comment Share on other sites More sharing options...
Jason Carr Posted December 16, 2022 Share Posted December 16, 2022 This does look to be an issue with .NET of some sort. It's probably worth uninstalling .NET Core 3.1 and reinstalling it from here: https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/runtime-desktop-3.1.32-windows-x64-installer You need the ".NET Desktop Runtime 3.1.32" for x64.
