  3. System Requirements
  ======================================================================
     Trend Micro recommends installing this hotfix on any of the 
     following Worry-Free Business Security versions: 

     - Worry-Free Business Security 9.5 
     - Worry-Free Business Security 10.0
     - Worry-Free Business Security 10.0 Service Pack 1


  4. Installation
  ======================================================================
     This section explains key steps for installing the hotfix.

     4.1 Installing
     ===================================================================
     To install:

     1. Copy the hotfix executable file to a temporary folder on the 
        server where the MSA is installed., for example, "C:\temp".

     2. Double-click the file. The modules are automatically copied to
        the correct destination.

     During installation, this hotfix installation package stops the 
     MS Exchange Transport Agent service and MSA services which in turn
     stops transport services. Users will not be able to receive and 
     send email messages during this Exchange server downtime.

     This hotfix installation package automatically rolls back the
     Messaging Security Agent to its previous configuration if there 
     are problems during installation.

     If you encounter problems after installation, do a manual rollback.
     

     4.2 Uninstalling
     ===================================================================
     To manually roll back to the previous configuration:

     1. Stop Trend Micro Messaging Security Agent Master Service.

     2. Locate the backup folder that the hotfix package created in the 
        "C:\Program Files\Trend Micro\Messaging Security Agent\HotFix\
        B-1073\BackupFile\" directory. 
   
     3. Copy the updated backup file to the corresponding folder.
   
     4. Restart the Trend Micro Messaging Security Agent Master Service.

     
  5. Post-installation Configuration
  ======================================================================
