Hi Sebastian, Thanks! I got it. One question though... Why is that when I used chktrust to verify the digital signature of EXCEL, WINWORD or POWERPNT.exe, the return is always like this:
/ *Mono CheckTrust - version 2.10.4.0 Verify if an PE executable has a valid Authenticode(tm) signature Copyright 2002, 2003 Motus Technologies. Copyright 2004-2008 Novell. BSD licensed. WARNING!
