I have come across a situation where my client was not able to download zip attachments embedded in PDF documents, though he was using latest version of Acrobat Reader. But we make use of Acrobat Professional 6 version to download zip attachments from the same PDF documents.
What about peoples who don’t have Acrobat Professional? Follow
- Open registry editor
- Navigate to following registry path
- Choose registry value: tBuiltInPermList
- Search for zip and change from 3 to 2
- Close all acrobat files and open again, user must be able to extract files now.
