I ran into some issues when installing the Sharepoint2003Scanner on the Web front end server of our Sharepoint Portal Server 2003 environment. I was getting a 14001 error, and wanted to share the fix.
SEVERE: exception in main thread
java.io.IOException: Cannot run program "E:/SharePoint2003Scanner/scanner/VontuSharePoint2003Scanner.exe": CreateProcess error=14001, This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem
This was due to the Microsoft Visual C ++ 2005 Redistributable package that the was installed during the Sharepoint implementation years ago. The Sharepoint Scanner for 2003 target requires the 2005 Redistributable package with ATL security. After download and installation, it requires a reboot, so make sure to schedule downtime if you don't have your web front ends clustered.
Remember if you want the scan to run as a service, change the log on account for the service to one with Sharepoint priveleges.
Can't wait till my company upgrades to Sharepoint 2010, I hear it integrates well with DLP Enforce version 11.
