User Guide PDF error with old version of Acrobat Reader: Damaged file

Question

When I try to open the User Guide PDF document I get an error:
"There was an error opening this document. The file is damaged and could not be repaired."
Old version Adobe Acrobat: Error damaged document

I also get the error when I click on the User Guide options from the ASAP Utilities Excel menu.

Answer

The problem lies within the use of an old version of Adobe Acrobat Reader.
We have been able to reproduce this error with Acrobat Reader 5, which dates from 2001. Upgrading to a new version solved the problem.

Please upgrade to the latest version of Adobe Acrobat Reader.
