I have run the update & rebooted twice. However, PSI still reports the problem version as being present. In checking the specific file versions, I see that acrobat.exe is in fact still version 9.4.2.220 and is dated 31-JAN-2011, but acrobat.dll is now version 9.4.3.231, and is dated 12-MAR-2011. Therefore, it appears to me that the update in fact did install successfully, but PSI is not checking the correct file(s) within the Acrobat 9 installation folder.

Hello ADX3018 ,

You may not be aware that the comments section under any Secunia Advisory is for technical discussion of the SA itself and the vulnerabilities ; your posting creates a thread in the "vulnerabilities" sub-Forum , but it is still limited to technical input regarding the specific SA .

Your problems are with the PSI itself and not relevant to the SA itself ; you need to create your own thread using a/the links in the column on the left hand side of this Forum page .

Take care

Anthony
