Microsoft Office 2010 File is Unscannable With Error Message: "Decomposer failed to open the container. at location printerSettings1.bin within printerSettings"

Products

• Mail Security for Microsoft Exchange

Issue/Introduction

Symantec Mail Security for Microsoft Exchange (SMSMSE) reports Microsoft Office 2010 files are unscannable with the following error message:

Scan Engine Error.  CSAPI DEC result: 0x11. Decomposer failed to open the container. at location printerSettings1.bin within printerSettings within xlsx

NOTE:  The file extension may be different.
 

Cause

The Printersettings1.bin files are detected as ARCManager container files. SMSMSE tries to open these files and fails causing the unscannable.

Resolution

This issue if fixed in SMSMSE 6.5.6, upgrade to 6.5.6 or later to resolve this problem.

 

Workaround

 

Configure SMSMSE to not perform scanning inside ARCManager files:

1. It is recommended that a backup of the registry be made prior to making any registry changes.
2. Download the appropriate attachment below and extract the registry file (.reg).
3. Double click on the registry file DecEngineList_Disable_AMG.reg.
4. A registry editor dialog box will appear with the message "Are you sure want to add the information to registry?”. Click on yes. 
5. Restart Symantec Mail Security for Microsoft Exchange service and Symantec Mail Security Utility Service.
