Hi Antero00,
According to your description. I do some search on this question and I found:
If you want to install .Net Framework 4.x in Windows Server 2019, the .Net Framework version must be
4.7.2 or 4.8. Because of the different supported platforms between different versions.
You could refer to this document below for more details:
Install the .NET Framework for developers
If I misunderstood something, please let me know.
Best regards,
