Unable to open a protected PDF with Adobe Reader

Jan 2, 2012 1:11 AM

Hi Guys,


I'm trying to understand how LC Righs Management works. So what i'm doing is following:

1. Protecting a PDF with a specific preconfigured right in my policy server by using Acrobat Pro.

2. Trying to open same fine in Adobe Reader gives me "An error occured while performing thsi operation. Contact an Administrator if this proplem continues".


Same file can be opend in acrobat pro without any problems.

My certificate is installed. (port is 8443)


Any ideas why ADobe Reader faisl to read a protected PDF?

    Is the SSL certificate trusted on the machine that Reader is installed on?  One quick way to test this is to access the LiveCycle server from a browser (https://servername:8443), if a security warning is displayed by the browser, then you know that the cert is not trusted on the system.  This will cause Reader to throw an error.

    What version or Rights Management was used to protect the PDF, and what are the exact versions of Acrobat Pro and Reader.  I can't recall exactly, but I think in the past there were some bugs where certain versions of reader would fail to open policy protected PDFs protected with a certain version of Rights Management.  Unfortunately, I can't remember the details.  You may want to contact Adobe technical support.
