Show another license page after finish main installation part using NSIS

Question

So, this is my current installer page structure:

!insertmacro MUI_PAGE_WELCOME
page custom CheckHWSpecs
!insertmacro MUI_PAGE_LICENSE "${SOURCEFOLDER}\CDA_update061702.txt"
!define MUI_DIRECTORYPAGE_VERIFYONLEAVE
!insertmacro MUI_PAGE_DIRECTORY
!insertmacro MUI_PAGE_STARTMENU Application $StartMenuGroup
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_PAGE_FINISH
!insertmacro MUI_UNPAGE_CONFIRM
!insertmacro MUI_UNPAGE_INSTFILES

When user finish installing the main application, I need to install a third-party application. Before start to install the 3rd-party app, I need to show another license page and if user agree, it will continue to install the app. But, if user disagree, it will cancel the 3rd-party app installation and the installation process is finish.

Can I do something like this?

!insertmacro MUI_PAGE_WELCOME
page custom CheckHWSpecs
!insertmacro MUI_PAGE_LICENSE "${SOURCEFOLDER}\CDA_update061702.txt"
!define MUI_DIRECTORYPAGE_VERIFYONLEAVE
!insertmacro MUI_PAGE_DIRECTORY
!insertmacro MUI_PAGE_STARTMENU Application $StartMenuGroup
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_PAGE_LICENSE "${SOURCEFOLDER}\license2.txt"
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_PAGE_FINISH
!insertmacro MUI_UNPAGE_CONFIRM
!insertmacro MUI_UNPAGE_INSTFILES

But if there are two !insertmacro MUI_PAGE_INSTFILES , how to make sure the 3rd-party installer will run in the second MUI_PAGE_INSTFILES?

Answer 1

• I would configure the 3rd -party app as another section (it can be hidden if the text is empty or by code with a SectionSetText ${SectionID} "" ).
• After the first licence page, use a custom page to display the 2nd license with a checkbox to accept it (IIRC you can use only one MUI_PAGE_LICENSE )
• depending on the result of the custom page (use a custom page leave callback to test for acceptance or not), check the hidden section with !insertmacro SelectSection ${SectionID}
• then during the execution of MUI_PAGE_INSTFILES your 3rd-party app will be installed (or not) like the main app.

!include Sections.nsh
!include WinMessages.nsh
ShowInstDetails show
!include MUI2.nsh
!insertmacro MUI_PAGE_WELCOME
!insertmacro MUI_PAGE_LICENSE "${NSISDIR}\Examples\example1.nsi"
!insertmacro MUI_PAGE_INSTFILES
!define MUI_LICENSEPAGE_CHECKBOX
!define MUI_LICENSEPAGE_CHECKBOX_TEXT "Blah blah blah app and agree..."
!define MUI_PAGE_CUSTOMFUNCTION_SHOW Lic2Show
!insertmacro MUI_PAGE_LICENSE "${NSISDIR}\Examples\example2.nsi"
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_PAGE_FINISH
!insertmacro MUI_LANGUAGE English

Section /o "Bonus app" SID_BONUS
DetailPrint "Installing bonus app..."
Sleep 2222
SectionEnd

Section "Main app" SID_MAIN
DetailPrint "Installing main app..."
Sleep 2222

!insertmacro SelectSection ${SID_BONUS}
!insertmacro UnselectSection ${SID_MAIN}
SectionEnd

Function Lic2Show
GetDlgItem $0 $hwndparent 2
SendMessage $0 ${WM_SETTEXT} 0 "STR:$(MUI_BUTTONTEXT_FINISH)"
FunctionEnd

If the user does not install the extra app then you never get to the finish page, the cancel button is just renamed to "Finish".
