Je crois que je viens de trouver avec la FAQ :
"You should not see a "ready to install" button during the normal game download flow in Origin.
Head to your game download folder. If it is the default one it should look like
C:\Program Files (x86)\Origin Games\Need for Speed The Run Limited Edition
Find Need for Speed the Run.exe.
If it looks instead like Need for Speed the Run.exe_DiP_STAGED, remove the _DiP_STAGED part from the game .exe
You should now be able to install NFS The Run without getting stuck."
Je me disais bien que ce _DiP_STAGED servait à rien
