If you are upgrading from Alfabet 11.11 or lower, you need to upgrade the underlying Microsoft® .NET component:
- Install .NET Desktop Runtime 10 and ASP.NET Core Runtime 10. You can download it from https://dotnet.microsoft.com/en-us/download/dotnet/10.0.
If you have not installed the .NET framework components prior to starting the Alfabet installer, the installer will ask you to install .NET and provide you with a download link. Both components are requested separately by the installer. After download and installation of .NET Dessktop Runtime, the installer need to be restarted to provide the download link for ASP.NET Core Runtime.
