如何为这两个安装自定义标题栏（设置名称）？

NSIS并不是专门为这一目的设计的，因此每次页面更改时，您都必须手动设置标题栏：

!include MUI.nsh
!include WinMessages.nsh
Caption " "

!define MUI_PAGE_CUSTOMFUNCTION_SHOW lic1
!insertmacro MUI_PAGE_LICENSE "${__FILE__}"
!define MUI_PAGE_CUSTOMFUNCTION_SHOW inst1
!insertmacro MUI_PAGE_INSTFILES
!define MUI_PAGE_CUSTOMFUNCTION_SHOW lic2
!insertmacro MUI_PAGE_LICENSE "${__FILE__}"
!define MUI_PAGE_CUSTOMFUNCTION_SHOW inst2
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_LANGUAGE English

Function lic1
SendMessage $HWNDPARENT ${WM_SETTEXT} 0 "STR:Foo$(^LicenseSubCaption)"
FunctionEnd
Function inst1
SendMessage $HWNDPARENT ${WM_SETTEXT} 0 "STR:Foo$(^InstallingSubCaption)"
FunctionEnd
Function lic2
SendMessage $HWNDPARENT ${WM_SETTEXT} 0 "STR:Bar$(^LicenseSubCaption)"
FunctionEnd
Function inst2
SendMessage $HWNDPARENT ${WM_SETTEXT} 0 "STR:Bar$(^InstallingSubCaption)"
FunctionEnd
