I'm at the moment signing technical drawings electronically with Acrobat Pro 7.
I would like that another people sign this document but with acrobat reader 9.
When I open the drawing, the digital signature menu is not available in Reader. No operation is permited.
I saw that it could be possible to do this operation with Reader by extending the Acrobat Reader functions form the advanced options menu.
But, the extension must be realised in Acrobat Pro or Acrobat Reader ?
Thanks in advance for your help.
