Hi,
i have exact the same issue with EGLL.
I changed my Flightsim pc and have iniManager on a remote machine.
On my old pc everything worked fine, but with the new machine, it seems iniManager has troubles with recognizing installed sceneries.
I had installed LOWI premium on my last machine, and it the manager app still thinks i have installed it.
So i deinstalled iniManager and downloaded the latest version from your website (after the deinstallation there is still data left in the appdata\local and appdata\roaming dir, for a clean new installation with initial setup they have to be deleted).
Anyway after the new installation, i had to setup everything from scratch and after setting the fs2024 path, the manager checks the installed scenery, but there is no config menu).
regards
Chris
