Function un.onGUIInit

Hi

I'm trying to call a function before the uninstall window appears. The following works perfectly:

outFile "installer.exe"

installDir $DESKTOP



section

  setOutPath $INSTDIR

  file test.txt

  writeUninstaller $INSTDIR\uninstaller.exe

sectionEnd





section "Uninstall"

  delete $INSTDIR\uninstaller.exe

  delete $INSTDIR\test.txt

sectionEnd



Function .onInit

    MessageBox MB_OK "before initialise."

FunctionEnd



Function un.onGUIInit

    MessageBox MB_OK "before uninstall."

FunctionEnd

However, the moment I add the function un.onGUIInit to my real script I get a compile error saying:

Function: "un.onGUIInit"
Error: Function named "un.onGUIInit" already exists.

But there is no other duplicate function within my script. It wasn't in any of the headers either.

Any ideas?

Cheers,

Paul

In my script I use MUI and I have just found out the following:

The MUI itself uses .onGUIInit and un.onGUIInit you should define a certain define to tell it to call your own function from its .onGUIInit. See the MUI readme for more information.

So I'm looking into that.

Cheers,

Paul

Check the MUI readme and look for MUI_CUSTOMFUNCTION_UNGUIINIT in the General Custom Functions section
