Application Detection Rule for MUI

Hi Everyone,

I'm deploying (or at least trying to) MUI for windows 10.

My problem is the DETECTION RULE, I've found out that when you installa a MUI in the registry of windows it's added under:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\MUI\UILanguages

And there you can find for example: it-IT, de-DE , ....

My problem is that I've tryed to put in the detection rule to find out the ""folder"" fr-FR, but it doesnt work.

Maybe im doing something wrong, the actual detection rule that I'm using is this one:

I've also tryed to use as detection method the value of the LCID key (REG_DWORD) but no luck...
