You have to go and change the language in the CC Desktop application in the preferences to Hebrew and install it again without unistalling.
Because of a problem it might help, to install also the Arabic version, as some menu elements are not available when you install hebrew alone as additional RTL language.
Thank you for your answer Willi,
I'm not sure I perfectly understand is it in the Dictionary option that I have to choose Hebrew ?
Thanks for your help
NO, you have to go to the CC Desktop Application.
CHange the application language there.
INstall your program again above your normal language.
Start the progam.
Thank you :-)
