[Framers] RTL support damaged in FM-15 and FM-14?

[Klaus Daube]

I installed FM-15.0.5.838 on the Wind10 machine of my wife - which is a plain vanilla 
installation - and the problem I have on my machine does not occur! Hence FM is 
definitely not the cause of the problem.
Although both machines have exactly the same Win10-status (OSbuild 10.0.18363.778) 
there is one noticable difference:

My machine has these directories: 
C:\Program Files\Common Files\Adobe\Linguistics and 
C:\Program Files (x86)\Common Files\Adobe\Linguistics and 
%AppData%\Adobe\Linguistics

Inge's machine: no such directories (after installen FM-15)

I really don't understand why these directories exist - the very same content can be 
found in each of my FM installations starting with FM-12:  
$HOME\FMxx\fminit\Linguistics

-> Renaming these Linguistics on C: to !_Linguistics did not make any difference for 
the problem.

So a more elaborate search for the culprit on my system starts ...

Any ideas are 
welcome!~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
