Since Quick Launch icons apparently aren't used in Windows 7, I want my installer not to present the user with the Quick Launch checkbox on the Components page if the user is running Windows 7.

First, to determine whether the user is running Windows 7, I have:

code:

Function .onInit
  Var /GLOBAL WindowsVersion
  ReadRegStr $R0 HKLM "SOFTWARE\Microsoft\Windows\CurrentVersion" VersionNumber
  StrCpy $R1 $R0 3
  StrCmp $R1 '6.1' 0 +2
  StrCpy $WindowsVersion "7"
FunctionEnd

code:

!define MUI_COMPONENTSPAGE_NODESC
!insertmacro MUI_PAGE_COMPONENTS

; ... [snip] ...

LangString LS_QuickLaunchIconSecName ${LANG_ENGLISH} \
           "Quick Launch icon"

; ... [snip] ...

Section "$(LS_QuickLaunchIconSecName)"
  CreateShortCut "$QUICKLAUNCH\${APP_NAME}.lnk" "$INSTDIR\${APP_NAME}.exe"
SectionEnd

don't read the registry to find the windows version, use winver.nsh

to disable/uncheck a section, the section needs an id, specify the id like so: section "display name" myId

then, somewhere _after_ that section in the script, you need to use a function that is called at runtime (.oninit,.onguiinit or the pre callback for the components page) and disable the section if needed using the helper macros in sections.nsh

OK, I now have:

code:

Section "$(LS_QuickLaunchIconSecName)" S_QuickLaunch
  CreateShortCut "$QUICKLAUNCH\${APP_NAME}.lnk" "$INSTDIR\${APP_NAME}.exe"
SectionEnd

; ... [snip] ...

Function .onInit
  ${If} ${IsWin7}
    UnselectSection S_QuickLaunch
  ${Endif}
FunctionEnd

section "name" id
...
UnselectSection ${id}

also, to _hide_ the item, you need to set its name to an empty string

D'oh! I realized I wasn't editing the copy of the file that was being used to generate the installer, so of course the result was no different.

Anyway, it works now that I'm editing the correct file. Thanks for your patience.
