Introduction
The installation of historical frameworks 2.0,3.0 and 3.5 on Windows 2019 does not work if the machine does not have an Internet connection or if it is connected to a WSUS server. To install these components in this case, it is recommended to use an ISO of Windows 2019.
Install NetFx3 without Internet access
By default, the 2.0 / 3.0 and 3.5 frameworks are not installed on Windows 2019.

To install them, you need to mount an ISO of Windows 2019.

You can then use the following command (with the ISO mounted on the letter E :):
dism /online /Enable-Feature /FeatureName:NetFx3 /Source:"E:\sources\sxs" /LimitAccess /all
The historical frameworks are then installed.

It is also necessary to force a Windows Update of the machine (via internal WSUS) to update installed frameworks.
