langstring ignored in .onInit
I am using the mutex detect function to see if my installer is running, which works great, but I want to have the correct language used for the messagebox warning. At the moment the LangString is ignored by the .onInit function, is there a way around this?

I am using 2.0b4.
I have attached an example script so you can see what I'm getting at.
Firewall blocked it, added as code:

LangString InstallerRunning ${LANG_ENGLISH} "English: The installer is already running."
LangString InstallerRunning ${LANG_FRENCH} "French: The installer is already running."
LangString InstallerRunning ${LANG_GERMAN} "German: The installer is already running."
LangString InstallerRunning ${LANG_DUTCH} "Dutch: The installer is already running."
LangString InstallerRunning ${LANG_HEBREW} "Hebrew: The installer is already running."

Function .onInit
  !insertmacro MUI_LANGDLL_DISPLAY
    System::Call 'kernel32::CreateMutexA(i 0, i 0, t "LangString") i .r1 ?e' 
        Pop $R0 
        StrCmp $R0 0 +3 
          MessageBox MB_OK $(InstallerRunning)
  Abort
FunctionEnd

Thanks. Any plans to change this behaviour?

Put the code in a custom GUIINIT function and it will work.

Yes, though I'm not sure when exactly. .onGUIInit isn't called when the installer is silent so it's not the best solution.

I just use a custom page as the first page which does the checks I want with the correct language in any message boxes. Its not a problem as such but would seem neater, IMHO, if it could be in onInit section instead but this is in no way urgent or anything :D

Keep up the good work.

You can use .onGuiInit or a Modern UI custom GUIINIT function, that's easier than adding an extra page.

The disadvantage of both methods is that is doesn't work in silent mode.
