When i want to open a PDF file by clicking on it on with the "Open with" menu. I got an Windows error :
"L'instruction à 0x000000007716E6D4 emploie l'adresse mémoire 0x00000000000000000. L'état de la mémoire ne peut être read".
I install again Acrobat Reader, but same error.
Thank's a lot for your answer.
