Hi Mark,

good questions.

When you said "installer background", do you mean the "blue" backgound behind the wizard dialogs? They are only there for backward compatibility reasons (to SetupBuilder 5).

The DPI stuff itself should be handled autamically by the Windows operating system. The setup.exe includes a manifest to support "DPI-awareness". Could you please send a screenshot from the dialog on your 4K monitor (not from the "blue" background because this is only there for backward compatibility and should not be used in modern installers).

BTW, and could you please launch this Microsoft MSI setup and post a screenshot from the MSI dialog on your 4K dialog.

Thanks Mark.
