I have a licensed copy Adobe Acrobat Reader 11.0.5. I am trying to digitally sign a .pdf file through the software with a digital certificate downloaded from the CA (Certificate Authority). The signed document says that the signature is invalid.
When I use the same token to sign using Acrobat Reader 6, the signature is proper. The signature done through Acrobat Reader 6 are easily validated on any system and any software. I think am missing some setting in Acrobat Reader 11. Please help.
