Section navigation

Hi all!

I'm new on this forum (it's my first post) but it's a long time I read this forum (and it's a long time I speak a bad english 😁).

My question :
I use a MUI_PAGE_CUSTOMFUNCTION_LEAVE function to check the choosen installation directory (MUI_PAGE_DIRECTORY).
If choosen installation directory is allready used by another install (I have to manage several clients), I ask the user to confirm overwrite.
If he confirms, the start menu section is skipped and the install gone at the end 👍.
If not, i want to reload the window where user chose the installation directory.

Is it possible?
How?

Thanks in advance.🙂

😱 Nobody's able to answer me ? 😢 😢

Be a little patient 🙂

Use Abort in the leave function to stay on the current page.

Thanks, it's work 😁

I thought that Abort was used to skip a section because when I use it in a MUI_PAGE_CUSTOMFUNCTION_PRE function (as following), the corresponding page (Start Menu here) is skipped.

!define MUI_PAGE_CUSTOMFUNCTION_PRE testOverwrite
!define MUI_STARTMENUPAGE_REGISTRY_ROOT "HKEY_LOCAL_MACHINE"
!define MUI_STARTMENUPAGE_REGISTRY_KEY "Software\$(^Name)\$CUR_CLIENT" 
!define MUI_STARTMENUPAGE_REGISTRY_VALUENAME "Start Menu Folder"
!insertmacro MUI_PAGE_STARTMENU Application $STARTMENU_FOLDER
Function testOverwrite
    StrCmp $OVERWRITE "" endOverwrite +1
    ReadRegStr $2 HKLM "Software\$(^Name)\$OVERWRITE" "Start Menu Folder"
    StrCpy $STARTMENU_FOLDER $2
    Abort
  endOverwrite:
FunctionEnd
