Can open files in NItro but not in Adobe Acrobat/Reader: XML Parsing Error

[Wayneskie]

Hello, 
Trying to get answers as to why im able to open this file in Nitro and not in Adobe Reader or Acrobat.

Looks like that Nitro ignores the error.

Thank you @Bernd Alheit , is there anything that I can do to make this to work for other users that only have Adobe Reader/Acrobat in their system?

Yes, remove the duplicate attribute.
