How to control Section selections

Hi, I have a problem: I have 4 components (A,B,C,D) to install.
1.if A is selected B can't be selected and C is automatically selected.
2. if B is selected C and A can't be selected
3. D can be selected with A,B,C
4. C can be selected alone.
I don't know how to do this. Could somebody help me?
Thanks!!

You could implement whichever logic you wish in .onSelChange. Examples\one-section.nsi shows how to implement a logic that forces only one section to be selected at a time. Macros are available in Include\Sections.nsh to make this job easier.

Thanks for your help. But i don't find a way to do what I want.Can you say me how I can do it please!

Hi mamilo!

Try this:

;--------------------------------

;Include Modern UI



  !define LOGICLIB_SECTIONCMP



  !include "MUI.nsh"

  !include "logiclib.nsh"

  !include "sections.nsh"



;--------------------------------

;General



  ;Name and file

  Name "Test"

  OutFile "test.exe"

  

;--------------------------------

;Pages



  !insertmacro MUI_PAGE_COMPONENTS

  !insertmacro MUI_PAGE_INSTFILES



Section !A secA

SectionEnd



Section /o !B secB

SectionEnd



Section C secC

SectionEnd



Section D secD

SectionEnd



Function .onSelChange



  ${If} ${SectionIsSelected} ${secB}

    !insertmacro UnSelectSection ${secA}

    !insertmacro UnSelectSection ${secC}

  ${EndIf}



  ${If} ${SectionIsSelected} ${secA}

    !insertmacro UnSelectSection ${secB}

    !insertmacro SelectSection ${secC}

  ${EndIf}



FunctionEnd
