Hi Obi-wan
The above link works on Mac
You gave me an idea to where to look for. I found a video by David Blatner on Youtube that actually worked without any environment modification from the Creative Cloud and the current application preferences.
Change the UI languaging in InDesign CS6 and CC | InDesign | lynda.com - YouTube
The steps are
Quit inDesign
RENAMING THE FOLLOWING FOLDERS "fr_FR" for French
C:\Program Files\Adobe\Adobe InDesign CC 2014\Presets\InDesign Workspaces\fr_FR
C:\Program Files\Adobe\Adobe InDesign CC 2014\Presets\InDesign Shortcut Sets\fr_FR
TO "en_US" for English
C:\Program Files\Adobe\Adobe InDesign CC 2014\Presets\InDesign Workspaces\en_US
C:\Program Files\Adobe\Adobe InDesign CC 2014\Presets\InDesign Shortcut Sets\en_US
Start inDesign
et Voilà
The workplace is not set we need
under Window menu
select Workspace Clic on "Avancée"
the workplace with the tool bar are back
Thanks again Obi-wan
