Happy new you year to you and all,
I will try to investigate installation on Windows 10 (19H1) 18305.
However, "Data Access Problem" is related to missing or disconnected hardware (like network card) or improperly installed drivers. The network card does not need to be connected to the internet, but it should be working and possible o connect.
It could also be related to a failing service due to missing / corrupt / wrong version files, for example having 2 versions of Java !!
