How can I add a header to the NSIS license page?

Question

The top of my NSIS license page looks rather stark:

I don't see any way to modify the header/subtitle of the page through the normal channels. LicenseText looks close, but it only seems to modify the text at the bottom of the dialog.

Is there any way to add a header to the page?

Answer 1

You must include a language to fully initialize the MUI:

!include "MUI.nsh"
!insertmacro MUI_PAGE_LICENSE "License.rtf"
!insertmacro MUI_PAGE_COMPONENTS
!insertmacro MUI_PAGE_...
!insertmacro MUI_LANGUAGE "English"

If you want to use a bitmap in the header and not the .exe icon, then you should look at the defines Seki talks about...
