Это, как раз, давно придумано :

Код:

OutFile ListBox_H-Scroll.exe
!include nsDialogs.nsh
Var Dialog
Var ReleaseNotesText
Page custom MyPage

Function MyPage
nsDialogs::Create 1018
Pop $Dialog

Pop $ReleaseNotesText
${NSD_LB_AddString} $ReleaseNotesText "A pretty loooooooooooooooooooooooooooooooooooooooooooooooong striiiiiiiiiiing"
${NSD_LB_AddString} $ReleaseNotesText "A really long string that should be longer than the listbox that contains this message, so I can enable the horizontal scrollbar!"
SendMessage $ReleaseNotesText ${WM_GETFONT} 0 0 $R0
System::Call user32::GetDC(i$ReleaseNotesText)i.R1
