I have the same issue of Hebrew support in Acrobat DC , when editing a Hebrew doc i get all letters swapped left to right.
tried to download the
but get an error message when installing.
at this stage looks that acrobat DC is not support right to left editing and sign.
would appreciate your attention to this ongoing issue.
