Error: The PDF document is damaged and cannot be repaired mainly because it is not a supported file type, or because the file is damaged (for example, it was sent as an email attachment and was not decoded correctly).
Solution: Use one of the following solutions
PDF creator
If you manage software that automatically generates PDF, please modify the way that PDF is generated. Make sure that there are no extra bytes before %PDF at the beginning of the file.
PDF users: corporate administrators and users
If you are a customer or corporate IT professional, you can disable header verification on your computer by setting the appropriate preferences. You can set this preference for each user in HKCU, or you can set this preference at the computer level for all users in HKLM. You can use a similar method on Mac OS by modifying the same plist preferences. If the AVGeneral key does not exist, create it manually.
The HKLM path is usually:
HKLM\software\Adobe\(product name)\(version)\AVGeneral\bValidateBytesBeforeHeader = dword: 00000000
For example, to change the behavior of Acrobat 11.0, create a dwORD in the following location: HKLM \ SOFTWARE \ Adobe \ Adobe Acrobat \ 11.0 \ AVGeneral \ bValidateBytesBeforeHeader = dword: 00000000
The HKCU path is generally:
HKCU\software\Adobe\(product name)\(version)\AVGeneral\bValidateBytesBeforeHeader = dword: 00000000
For example, to change the behavior of Reader 10.0, please create a dwORD in the following location: HKCU \ SOFTWARE \ Adobe \ Acrobat Reader \ 10.0 \ AVGeneral \ bValidateBytesBeforeHeader = dword: 00000000
Always change the product and version number in the preference path to match your installation. This method allows the PDF to be displayed on the computer you control.
