Qt IFW: How to check if we are in maintanance mode

[lacuna]

Hi there,

I need to determine if the actual application is the "Intial Installer or the "Maintanancetool".
How can I do this? installer.isInstaller did not helped, because in maintenance mode it also gives a "true". Actually I am using IFW 4.11 on MacOS Tahoe or Sequoia.

Regards Alexander
